 # Go Memory Optimization
 ## Overview
 This skill provides guidance on optimizing Go programs for memory efficiency and reduced garbage collection overhead. Topics include stack allocation semantics, fixed-size types, escape analysis, object pooling, goroutine management, and GC tuning.
 ## Core Principles
 ### The Allocation Hierarchy
 Prefer allocations in this order (fastest to slowest):
 1. **Stack allocation** - Zero GC cost, automatic cleanup on function return
 2. **Pooled objects** - Amortized allocation cost via sync.Pool
 3. **Pre-allocated buffers** - Single allocation, reused across operations
 4. **Heap allocation** - GC-managed, use when lifetime exceeds function scope
 ### When Optimization Matters
 Focus memory optimization efforts on:
 - Hot paths executed thousands/millions of times per second
 - Large objects (>32KB) that stress the GC
 - Long-running services where GC pauses affect latency
 - Memory-constrained environments
 Avoid premature optimization. Profile first with `go tool pprof` to identify actual bottlenecks.
 ## Fixed-Size Types vs Slices
 ### Stack Allocation with Arrays
 Arrays with known compile-time size can be stack-allocated, avoiding heap entirely:
 ```go
 // HEAP: slice header + backing array escape to heap
 func processSlice() []byte {
    data := make([]byte, 32)
    // ... use data
    return data  // escapes
 }
 // STACK: fixed array stays on stack if doesn't escape
 func processArray() {
    var data [32]byte  // stack-allocated
    // ... use data
 }   // automatically cleaned up
 ```
 ### Fixed-Size Binary Types Pattern
 Define types with explicit sizes for protocol fields, cryptographic values, and identifiers:
 ```go
 // Binary types enforce length and enable stack allocation
 type EventID [32]byte      // SHA256 hash
 type Pubkey [32]byte       // Schnorr public key
 type Signature [64]byte    // Schnorr signature
 // Methods operate on value receivers when size permits
 func (id EventID) Hex() string {
    return hex.EncodeToString(id[:])
 }
 func (id EventID) IsZero() bool {
    return id == EventID{}  // efficient zero-value comparison
 }
 ```
 ### Size Thresholds
 | Size | Recommendation |
 |------|----------------|
 | ≤64 bytes | Pass by value, stack-friendly |
 | 65-128 bytes | Consider context; value for read-only, pointer for mutation |
 | >128 bytes | Pass by pointer to avoid copy overhead |
 ### Array to Slice Conversion
 Convert fixed arrays to slices only at API boundaries:
 ```go
 type Hash [32]byte
 func (h Hash) Bytes() []byte {
    return h[:]  // creates slice header, array stays on stack if h does
 }
 // Prefer methods that accept arrays directly
 func VerifySignature(pubkey Pubkey, msg []byte, sig Signature) bool {
    // pubkey and sig are stack-allocated in caller
 }
 ```
 ## Escape Analysis
 ### Understanding Escape
 Variables "escape" to the heap when the compiler cannot prove their lifetime is bounded by the stack frame. Check escape behavior with:
 ```bash
 go build -gcflags="-m -m" ./...
 ```
 ### Common Escape Causes
 ```go
 // 1. Returning pointers to local variables
 func escapes() *int {
    x := 42
    return &x  // x escapes
 }
 // 2. Storing in interface{}
 func escapes(x int) interface{} {
    return x  // x escapes (boxed)
 }
 // 3. Closures capturing by reference
 func escapes() func() int {
    x := 42
    return func() int { return x }  // x escapes
 }
 // 4. Slice/map with unknown capacity
 func escapes(n int) []byte {
    return make([]byte, n)  // escapes (size unknown at compile time)
 }
 // 5. Sending pointers to channels
 func escapes(ch chan *int) {
    x := 42
    ch <- &x  // x escapes
 }
 ```
 ### Preventing Escape
 ```go
 // 1. Accept pointers, don't return them
 func noEscape(result *[32]byte) {
    // caller owns memory, function fills it
    copy(result[:], computeHash())
 }
 // 2. Use fixed-size arrays
 func noEscape() {
    var buf [1024]byte  // known size, stack-allocated
    process(buf[:])
 }
 // 3. Preallocate with known capacity
 func noEscape() {
    buf := make([]byte, 0, 1024)  // may stay on stack
    // ... append up to 1024 bytes
 }
 // 4. Avoid interface{} on hot paths
 func noEscape(x int) int {
    return x * 2  // no boxing
 }
 ```
 ## sync.Pool Usage
 ### Basic Pattern
 ```go
 var bufferPool = sync.Pool{
    New: func() interface{} {
        return make([]byte, 0, 4096)
    },
 }
 func processRequest(data []byte) {
    buf := bufferPool.Get().([]byte)
    buf = buf[:0]  // reset length, keep capacity
    defer bufferPool.Put(buf)
    // use buf...
 }
 ```
 ### Typed Pool Wrapper
 ```go
 type BufferPool struct {
    pool sync.Pool
    size int
 }
 func NewBufferPool(size int) *BufferPool {
    return &BufferPool{
        pool: sync.Pool{
            New: func() interface{} {
                b := make([]byte, size)
                return &b
            },
        },
        size: size,
    }
 }
 func (p *BufferPool) Get() *[]byte {
    return p.pool.Get().(*[]byte)
 }
 func (p *BufferPool) Put(b *[]byte) {
    if b == nil || cap(*b) < p.size {
        return  // don't pool undersized buffers
    }
    *b = (*b)[:p.size]  // reset to full size
    p.pool.Put(b)
 }
 ```
 ### Pool Anti-Patterns
 ```go
 // BAD: Pool of pointers to small values (overhead exceeds benefit)
 var intPool = sync.Pool{New: func() interface{} { return new(int) }}
 // BAD: Not resetting state before Put
 bufPool.Put(buf)  // may contain sensitive data
 // BAD: Pooling objects with goroutine-local state
 var connPool = sync.Pool{...}  // connections are stateful
 // BAD: Assuming pooled objects persist (GC clears pools)
 obj := pool.Get()
 // ... long delay
 pool.Put(obj)  // obj may have been GC'd during delay
 ```
 ### When to Use sync.Pool
 | Use Case | Pool? | Reason |
 |----------|-------|--------|
 | Buffers in HTTP handlers | Yes | High allocation rate, short lifetime |
 | Encoder/decoder state | Yes | Expensive to initialize |
 | Small values (<64 bytes) | No | Pointer overhead exceeds benefit |
 | Long-lived objects | No | Pools are for short-lived reuse |
 | Objects with cleanup needs | No | Pool provides no finalization |
 ## Goroutine Pooling
 ### Worker Pool Pattern
 ```go
 type WorkerPool struct {
    jobs    chan func()
    workers int
    wg      sync.WaitGroup
 }
 func NewWorkerPool(workers, queueSize int) *WorkerPool {
    p := &WorkerPool{
        jobs:    make(chan func(), queueSize),
        workers: workers,
    }
    p.wg.Add(workers)
    for i := 0; i < workers; i++ {
        go p.worker()
    }
    return p
 }
 func (p *WorkerPool) worker() {
    defer p.wg.Done()
    for job := range p.jobs {
        job()
    }
 }
 func (p *WorkerPool) Submit(job func()) {
    p.jobs <- job
 }
 func (p *WorkerPool) Shutdown() {
    close(p.jobs)
    p.wg.Wait()
 }
 ```
 ### Bounded Concurrency with Semaphore
 ```go
 type Semaphore struct {
    sem chan struct{}
 }
 func NewSemaphore(n int) *Semaphore {
    return &Semaphore{sem: make(chan struct{}, n)}
 }
 func (s *Semaphore) Acquire() { s.sem <- struct{}{} }
 func (s *Semaphore) Release() { <-s.sem }
 // Usage
 sem := NewSemaphore(runtime.GOMAXPROCS(0))
 for _, item := range items {
    sem.Acquire()
    go func(it Item) {
        defer sem.Release()
        process(it)
    }(item)
 }
 ```
 ### Goroutine Reuse Benefits
 | Metric | Spawn per request | Worker pool |
 |--------|-------------------|-------------|
 | Goroutine creation | O(n) | O(workers) |
 | Stack allocation | 2KB × n | 2KB × workers |
 | Scheduler overhead | Higher | Lower |
 | GC pressure | Higher | Lower |
 ## Reducing GC Pressure
 ### Allocation Reduction Strategies
 ```go
 // 1. Reuse buffers across iterations
 buf := make([]byte, 0, 4096)
 for _, item := range items {
    buf = buf[:0]  // reset without reallocation
    buf = processItem(buf, item)
 }
 // 2. Preallocate slices with known length
 result := make([]Item, 0, len(input))  // avoid append reallocations
 for _, in := range input {
    result = append(result, transform(in))
 }
 // 3. Struct embedding instead of pointer fields
 type Event struct {
    ID        [32]byte    // embedded, not *[32]byte
    Pubkey    [32]byte    // single allocation for entire struct
    Signature [64]byte
    Content   string      // only string data on heap
 }
 // 4. String interning for repeated values
 var kindStrings = map[int]string{
    0: "set_metadata",
    1: "text_note",
    // ...
 }
 ```
 ### GC Tuning
 ```go
 import "runtime/debug"
 func init() {
    // GOGC: target heap growth percentage (default 100)
    // Lower = more frequent GC, less memory
    // Higher = less frequent GC, more memory
    debug.SetGCPercent(50)  // GC when heap grows 50%
    // GOMEMLIMIT: soft memory limit (Go 1.19+)
    // GC becomes more aggressive as limit approaches
    debug.SetMemoryLimit(512 << 20)  // 512MB limit
 }
 ```
 Environment variables:
 ```bash
 GOGC=50              # More aggressive GC
 GOMEMLIMIT=512MiB    # Soft memory limit
 GODEBUG=gctrace=1    # GC trace output
 ```
 ### Arena Allocation (Go 1.20+, experimental)
 ```go
 //go:build goexperiment.arenas
 import "arena"
 func processLargeDataset(data []byte) Result {
    a := arena.NewArena()
    defer a.Free()  // bulk free all allocations
    // All allocations from arena are freed together
    items := arena.MakeSlice[Item](a, 0, 1000)
    // ... process
    // Copy result out before Free
    return copyResult(result)
 }
 ```
 ## Memory Profiling
 ### Heap Profile
 ```go
 import "runtime/pprof"
 func captureHeapProfile() {
    f, _ := os.Create("heap.prof")
    defer f.Close()
    runtime.GC()  // get accurate picture
    pprof.WriteHeapProfile(f)
 }
 ```
 ```bash
 go tool pprof -http=:8080 heap.prof
 go tool pprof -alloc_space heap.prof  # total allocations
 go tool pprof -inuse_space heap.prof  # current usage
 ```
 ### Allocation Benchmarks
 ```go
 func BenchmarkAllocation(b *testing.B) {
    b.ReportAllocs()
    for i := 0; i < b.N; i++ {
        result := processData(input)
        _ = result
    }
 }
 ```
 Output interpretation:
 ```
 BenchmarkAllocation-8  1000000  1234 ns/op  256 B/op  3 allocs/op
                                            ↑         ↑
                                   bytes/op   allocations/op
 ```
 ### Live Memory Monitoring
 ```go
 func printMemStats() {
    var m runtime.MemStats
    runtime.ReadMemStats(&m)
    fmt.Printf("Alloc: %d MB\n", m.Alloc/1024/1024)
    fmt.Printf("TotalAlloc: %d MB\n", m.TotalAlloc/1024/1024)
    fmt.Printf("Sys: %d MB\n", m.Sys/1024/1024)
    fmt.Printf("NumGC: %d\n", m.NumGC)
    fmt.Printf("GCPause: %v\n", time.Duration(m.PauseNs[(m.NumGC+255)%256]))
 }
 ```

 # Go Memory Optimization Patterns
 Detailed code examples and patterns for memory-efficient Go programming.
 ## Buffer Pool Implementations
 ### Tiered Buffer Pool
 For workloads with varying buffer sizes:
 ```go
 type TieredPool struct {
    small  sync.Pool  // 1KB
    medium sync.Pool  // 16KB
    large  sync.Pool  // 256KB
 }
 func NewTieredPool() *TieredPool {
    return &TieredPool{
        small:  sync.Pool{New: func() interface{} { return make([]byte, 1024) }},
        medium: sync.Pool{New: func() interface{} { return make([]byte, 16384) }},
        large:  sync.Pool{New: func() interface{} { return make([]byte, 262144) }},
    }
 }
 func (p *TieredPool) Get(size int) []byte {
    switch {
    case size <= 1024:
        return p.small.Get().([]byte)[:size]
    case size <= 16384:
        return p.medium.Get().([]byte)[:size]
    case size <= 262144:
        return p.large.Get().([]byte)[:size]
    default:
        return make([]byte, size)  // too large for pool
    }
 }
 func (p *TieredPool) Put(b []byte) {
    switch cap(b) {
    case 1024:
        p.small.Put(b[:cap(b)])
    case 16384:
        p.medium.Put(b[:cap(b)])
    case 262144:
        p.large.Put(b[:cap(b)])
    }
    // Non-standard sizes are not pooled
 }
 ```
 ### bytes.Buffer Pool
 ```go
 var bufferPool = sync.Pool{
    New: func() interface{} {
        return new(bytes.Buffer)
    },
 }
 func GetBuffer() *bytes.Buffer {
    return bufferPool.Get().(*bytes.Buffer)
 }
 func PutBuffer(b *bytes.Buffer) {
    b.Reset()
    bufferPool.Put(b)
 }
 // Usage
 func processData(data []byte) string {
    buf := GetBuffer()
    defer PutBuffer(buf)
    buf.WriteString("prefix:")
    buf.Write(data)
    buf.WriteString(":suffix")
    return buf.String()  // allocates new string
 }
 ```
 ## Zero-Allocation JSON Encoding
 ### Pre-allocated Encoder
 ```go
 type JSONEncoder struct {
    buf    []byte
    scratch [64]byte  // for number formatting
 }
 func (e *JSONEncoder) Reset() {
    e.buf = e.buf[:0]
 }
 func (e *JSONEncoder) Bytes() []byte {
    return e.buf
 }
 func (e *JSONEncoder) WriteString(s string) {
    e.buf = append(e.buf, '"')
    for i := 0; i < len(s); i++ {
        c := s[i]
        switch c {
        case '"':
            e.buf = append(e.buf, '\\', '"')
        case '\\':
            e.buf = append(e.buf, '\\', '\\')
        case '\n':
            e.buf = append(e.buf, '\\', 'n')
        case '\r':
            e.buf = append(e.buf, '\\', 'r')
        case '\t':
            e.buf = append(e.buf, '\\', 't')
        default:
            if c < 0x20 {
                e.buf = append(e.buf, '\\', 'u', '0', '0',
                    hexDigits[c>>4], hexDigits[c&0xf])
            } else {
                e.buf = append(e.buf, c)
            }
        }
    }
    e.buf = append(e.buf, '"')
 }
 func (e *JSONEncoder) WriteInt(n int64) {
    e.buf = strconv.AppendInt(e.buf, n, 10)
 }
 func (e *JSONEncoder) WriteHex(b []byte) {
    e.buf = append(e.buf, '"')
    for _, v := range b {
        e.buf = append(e.buf, hexDigits[v>>4], hexDigits[v&0xf])
    }
    e.buf = append(e.buf, '"')
 }
 var hexDigits = [16]byte{'0', '1', '2', '3', '4', '5', '6', '7',
                          '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'}
 ```
 ### Append-Based Encoding
 ```go
 // AppendJSON appends JSON representation to dst, returning extended slice
 func (ev *Event) AppendJSON(dst []byte) []byte {
    dst = append(dst, `{"id":"`...)
    dst = appendHex(dst, ev.ID[:])
    dst = append(dst, `","pubkey":"`...)
    dst = appendHex(dst, ev.Pubkey[:])
    dst = append(dst, `","created_at":`...)
    dst = strconv.AppendInt(dst, ev.CreatedAt, 10)
    dst = append(dst, `,"kind":`...)
    dst = strconv.AppendInt(dst, int64(ev.Kind), 10)
    dst = append(dst, `,"content":`...)
    dst = appendJSONString(dst, ev.Content)
    dst = append(dst, '}')
    return dst
 }
 // Usage with pre-allocated buffer
 func encodeEvents(events []Event) []byte {
    // Estimate size: ~500 bytes per event
    buf := make([]byte, 0, len(events)*500)
    buf = append(buf, '[')
    for i, ev := range events {
        if i > 0 {
            buf = append(buf, ',')
        }
        buf = ev.AppendJSON(buf)
    }
    buf = append(buf, ']')
    return buf
 }
 ```
 ## Memory-Efficient String Building
 ### strings.Builder with Preallocation
 ```go
 func buildQuery(parts []string) string {
    // Calculate total length
    total := len(parts) - 1  // for separators
    for _, p := range parts {
        total += len(p)
    }
    var b strings.Builder
    b.Grow(total)  // single allocation
    for i, p := range parts {
        if i > 0 {
            b.WriteByte(',')
        }
        b.WriteString(p)
    }
    return b.String()
 }
 ```
 ### Avoiding String Concatenation
 ```go
 // BAD: O(n^2) allocations
 func buildPath(parts []string) string {
    result := ""
    for _, p := range parts {
        result += "/" + p  // new allocation each iteration
    }
    return result
 }
 // GOOD: O(n) with single allocation
 func buildPath(parts []string) string {
    if len(parts) == 0 {
        return ""
    }
    n := len(parts)  // for slashes
    for _, p := range parts {
        n += len(p)
    }
    b := make([]byte, 0, n)
    for _, p := range parts {
        b = append(b, '/')
        b = append(b, p...)
    }
    return string(b)
 }
 ```
 ### Unsafe String/Byte Conversion
 ```go
 import "unsafe"
 // Zero-allocation string to []byte (read-only!)
 func unsafeBytes(s string) []byte {
    return unsafe.Slice(unsafe.StringData(s), len(s))
 }
 // Zero-allocation []byte to string (b must not be modified!)
 func unsafeString(b []byte) string {
    return unsafe.String(unsafe.SliceData(b), len(b))
 }
 // Use when:
 // 1. Converting string for read-only operations (hashing, comparison)
 // 2. Returning []byte from buffer that won't be modified
 // 3. Performance-critical paths with careful ownership management
 ```
 ## Slice Capacity Management
 ### Append Growth Patterns
 ```go
 // Slice growth: 0 -> 1 -> 2 -> 4 -> 8 -> 16 -> 32 -> 64 -> ...
 // After 1024: grows by 25% each time
 // BAD: Unknown final size causes multiple reallocations
 func collectItems() []Item {
    var items []Item
    for item := range source {
        items = append(items, item)  // may reallocate multiple times
    }
    return items
 }
 // GOOD: Preallocate when size is known
 func collectItems(n int) []Item {
    items := make([]Item, 0, n)
    for item := range source {
        items = append(items, item)
    }
    return items
 }
 // GOOD: Use slice header trick for uncertain sizes
 func collectItems() []Item {
    items := make([]Item, 0, 32)  // reasonable initial capacity
    for item := range source {
        items = append(items, item)
    }
    // Trim excess capacity if items will be long-lived
    return items[:len(items):len(items)]
 }
 ```
 ### Slice Recycling
 ```go
 // Reuse slice backing array
 func processInBatches(items []Item, batchSize int) {
    batch := make([]Item, 0, batchSize)
    for i, item := range items {
        batch = append(batch, item)
        if len(batch) == batchSize || i == len(items)-1 {
            processBatch(batch)
            batch = batch[:0]  // reset length, keep capacity
        }
    }
 }
 ```
 ### Preventing Slice Memory Leaks
 ```go
 // BAD: Subslice keeps entire backing array alive
 func getFirst10(data []byte) []byte {
    return data[:10]  // entire data array stays in memory
 }
 // GOOD: Copy to release original array
 func getFirst10(data []byte) []byte {
    result := make([]byte, 10)
    copy(result, data[:10])
    return result
 }
 // Alternative: explicit capacity limit
 func getFirst10(data []byte) []byte {
    return data[:10:10]  // cap=10, can't accidentally grow into original
 }
 ```
 ## Struct Layout Optimization
 ### Field Ordering for Alignment
 ```go
 // BAD: 32 bytes due to padding
 type BadLayout struct {
    a bool      // 1 byte + 7 padding
    b int64     // 8 bytes
    c bool      // 1 byte + 7 padding
    d int64     // 8 bytes
 }
 // GOOD: 24 bytes with optimal ordering
 type GoodLayout struct {
    b int64     // 8 bytes
    d int64     // 8 bytes
    a bool      // 1 byte
    c bool      // 1 byte + 6 padding
 }
 // Rule: Order fields from largest to smallest alignment
 ```
 ### Checking Struct Size
 ```go
 func init() {
    // Compile-time size assertions
    var _ [24]byte = [unsafe.Sizeof(GoodLayout{})]byte{}
    // Or runtime check
    if unsafe.Sizeof(Event{}) > 256 {
        panic("Event struct too large")
    }
 }
 ```
 ### Cache-Line Optimization
 ```go
 const CacheLineSize = 64
 // Pad struct to prevent false sharing in concurrent access
 type PaddedCounter struct {
    value uint64
    _     [CacheLineSize - 8]byte  // padding
 }
 type Counters struct {
    reads  PaddedCounter
    writes PaddedCounter
    // Each counter on separate cache line
 }
 ```
 ## Object Reuse Patterns
 ### Reset Methods
 ```go
 type Request struct {
    Method  string
    Path    string
    Headers map[string]string
    Body    []byte
 }
 func (r *Request) Reset() {
    r.Method = ""
    r.Path = ""
    // Reuse map, just clear entries
    for k := range r.Headers {
        delete(r.Headers, k)
    }
    r.Body = r.Body[:0]
 }
 var requestPool = sync.Pool{
    New: func() interface{} {
        return &Request{
            Headers: make(map[string]string, 8),
            Body:    make([]byte, 0, 1024),
        }
    },
 }
 ```
 ### Flyweight Pattern
 ```go
 // Share immutable parts across many instances
 type Event struct {
    kind    *Kind   // shared, immutable
    content string
 }
 type Kind struct {
    ID          int
    Name        string
    Description string
 }
 var kindRegistry = map[int]*Kind{
    0: {0, "set_metadata", "User metadata"},
    1: {1, "text_note", "Text note"},
    // ... pre-allocated, shared across all events
 }
 func NewEvent(kindID int, content string) Event {
    return Event{
        kind:    kindRegistry[kindID],  // no allocation
        content: content,
    }
 }
 ```
 ## Channel Patterns for Memory Efficiency
 ### Buffered Channels as Object Pools
 ```go
 type SimplePool struct {
    pool chan *Buffer
 }
 func NewSimplePool(size int) *SimplePool {
    p := &SimplePool{pool: make(chan *Buffer, size)}
    for i := 0; i < size; i++ {
        p.pool <- NewBuffer()
    }
    return p
 }
 func (p *SimplePool) Get() *Buffer {
    select {
    case b := <-p.pool:
        return b
    default:
        return NewBuffer()  // pool empty, allocate new
    }
 }
 func (p *SimplePool) Put(b *Buffer) {
    select {
    case p.pool <- b:
    default:
        // pool full, let GC collect
    }
 }
 ```
 ### Batch Processing Channels
 ```go
 // Reduce channel overhead by batching
 func batchProcessor(input <-chan Item, batchSize int) <-chan []Item {
    output := make(chan []Item)
    go func() {
        defer close(output)
        batch := make([]Item, 0, batchSize)
        for item := range input {
            batch = append(batch, item)
            if len(batch) == batchSize {
                output <- batch
                batch = make([]Item, 0, batchSize)
            }
        }
        if len(batch) > 0 {
            output <- batch
        }
    }()
    return output
 }
 ```
 ## Advanced Techniques
 ### Manual Memory Management with mmap
 ```go
 import "golang.org/x/sys/unix"
 // Allocate memory outside Go heap
 func allocateMmap(size int) ([]byte, error) {
    data, err := unix.Mmap(-1, 0, size,
        unix.PROT_READ|unix.PROT_WRITE,
        unix.MAP_ANON|unix.MAP_PRIVATE)
    return data, err
 }
 func freeMmap(data []byte) error {
    return unix.Munmap(data)
 }
 ```
 ### Inline Arrays in Structs
 ```go
 // Small-size optimization: inline for small, pointer for large
 type SmallVec struct {
    len   int
    small [8]int      // inline storage for ≤8 elements
    large []int       // heap storage for >8 elements
 }
 func (v *SmallVec) Append(x int) {
    if v.large != nil {
        v.large = append(v.large, x)
        v.len++
        return
    }
    if v.len < 8 {
        v.small[v.len] = x
        v.len++
        return
    }
    // Spill to heap
    v.large = make([]int, 9, 16)
    copy(v.large, v.small[:])
    v.large[8] = x
    v.len++
 }
 ```
 ### Bump Allocator
 ```go
 // Simple arena-style allocator for batch allocations
 type BumpAllocator struct {
    buf []byte
    off int
 }
 func NewBumpAllocator(size int) *BumpAllocator {
    return &BumpAllocator{buf: make([]byte, size)}
 }
 func (a *BumpAllocator) Alloc(size int) []byte {
    if a.off+size > len(a.buf) {
        panic("bump allocator exhausted")
    }
    b := a.buf[a.off : a.off+size]
    a.off += size
    return b
 }
 func (a *BumpAllocator) Reset() {
    a.off = 0
 }
 // Usage: allocate many small objects, reset all at once
 func processBatch(items []Item) {
    arena := NewBumpAllocator(1 << 20)  // 1MB
    defer arena.Reset()
    for _, item := range items {
        buf := arena.Alloc(item.Size())
        item.Serialize(buf)
    }
 }

 # ORLY Relay Memory Optimization Analysis
 This document analyzes ORLY's current memory optimization patterns against Go best practices for high-performance systems. The analysis covers buffer management, caching strategies, allocation patterns, and identifies optimization opportunities.
 ## Executive Summary
 ORLY implements several sophisticated memory optimization strategies:
 - **Compact event storage** achieving ~87% space savings via serial references
 - **Two-level caching** for serial lookups and query results
 - **ZSTD compression** for query cache with LRU eviction
 - **Atomic operations** for lock-free statistics tracking
 - **Pre-allocation patterns** for slice capacity management
 However, several opportunities exist to further reduce GC pressure:
 - Implement `sync.Pool` for frequently allocated buffers
 - Use fixed-size arrays for cryptographic values
 - Pool `bytes.Buffer` instances in hot paths
 - Optimize escape behavior in serialization code
 ---
 ## Current Memory Patterns
 ### 1. Compact Event Storage
 **Location**: `pkg/database/compact_event.go`
 ORLY's most significant memory optimization is the compact binary format for event storage:
 ```
 Original event:  32 (ID) + 32 (pubkey) + 32*4 (tags) = 192+ bytes
 Compact format:   5 (pubkey serial) + 5*4 (tag serials) = 25 bytes
 Savings: ~87% compression per event
 ```
 **Key techniques:**
 - 5-byte serial references replace 32-byte IDs/pubkeys
 - Varint encoding for variable-length integers (CreatedAt, tag counts)
 - Type flags for efficient deserialization
 - Separate `SerialEventId` index for ID reconstruction
 **Assessment**: Excellent storage optimization. This dramatically reduces database size and I/O costs.
 ### 2. Serial Cache System
 **Location**: `pkg/database/serial_cache.go`
 Two-way lookup cache for serial ↔ ID/pubkey mappings:
 ```go
 type SerialCache struct {
    pubkeyBySerial     map[uint64][]byte      // For decoding
    serialByPubkeyHash map[string]uint64      // For encoding
    eventIdBySerial    map[uint64][]byte      // For decoding
    serialByEventIdHash map[string]uint64     // For encoding
 }
 ```
 **Memory footprint:**
 - Pubkey cache: 100k entries × 32 bytes ≈ 3.2MB
 - Event ID cache: 500k entries × 32 bytes ≈ 16MB
 - Total: ~19-20MB overhead
 **Strengths:**
 - Fine-grained `RWMutex` locking per direction/type
 - Configurable cache limits
 - Defensive copying prevents external mutations
 **Improvement opportunity:** The eviction strategy (clear 50% when full) is simple but not LRU. Consider ring buffers or generational caching for better hit rates.
 ### 3. Query Cache with ZSTD Compression
 **Location**: `pkg/database/querycache/event_cache.go`
 ```go
 type EventCache struct {
    entries   map[string]*EventCacheEntry
    lruList   *list.List
    encoder   *zstd.Encoder  // Reused encoder (level 9)
    decoder   *zstd.Decoder  // Reused decoder
    maxSize   int64          // Default 512MB compressed
 }
 ```
 **Strengths:**
 - ZSTD level 9 compression (best ratio)
 - Encoder/decoder reuse avoids repeated initialization
 - LRU eviction with proper size tracking
 - Background cleanup of expired entries
 - Tracks compression ratio with exponential moving average
 **Memory pattern:** Stores compressed data in cache, decompresses on-demand. This trades CPU for memory.
 ### 4. Buffer Allocation Patterns
 **Current approach:** Uses `new(bytes.Buffer)` throughout serialization code:
 ```go
 // pkg/database/save-event.go, compact_event.go, serial_cache.go
 buf := new(bytes.Buffer)
 // ... encode data
 return buf.Bytes()
 ```
 **Assessment:** Each call allocates a new buffer on the heap. For high-throughput scenarios (thousands of events/second), this creates significant GC pressure.
 ---
 ## Optimization Opportunities
 ### 1. Implement sync.Pool for Buffer Reuse
 **Priority: High**
 Currently, ORLY creates new `bytes.Buffer` instances for every serialization operation. A buffer pool would amortize allocation costs:
 ```go
 // Recommended implementation
 var bufferPool = sync.Pool{
    New: func() interface{} {
        return bytes.NewBuffer(make([]byte, 0, 4096))
    },
 }
 func getBuffer() *bytes.Buffer {
    return bufferPool.Get().(*bytes.Buffer)
 }
 func putBuffer(buf *bytes.Buffer) {
    buf.Reset()
    bufferPool.Put(buf)
 }
 ```
 **Impact areas:**
 - `pkg/database/compact_event.go` - MarshalCompactEvent, encodeCompactTag
 - `pkg/database/save-event.go` - index key generation
 - `pkg/database/serial_cache.go` - GetEventIdBySerial, StoreEventIdSerial
 **Expected benefit:** 50-80% reduction in buffer allocations on hot paths.
 ### 2. Fixed-Size Array Types for Cryptographic Values
 **Priority: Medium**
 The external nostr library uses `[]byte` slices for IDs, pubkeys, and signatures. However, these are always fixed sizes:
 | Type | Size | Current | Recommended |
 |------|------|---------|-------------|
 | Event ID | 32 bytes | `[]byte` | `[32]byte` |
 | Pubkey | 32 bytes | `[]byte` | `[32]byte` |
 | Signature | 64 bytes | `[]byte` | `[64]byte` |
 Internal types like `Uint40` already follow this pattern but use struct wrapping:
 ```go
 // Current (pkg/database/indexes/types/uint40.go)
 type Uint40 struct{ value uint64 }
 // Already efficient - no slice allocation
 ```
 For cryptographic values, consider wrapper types:
 ```go
 type EventID [32]byte
 type Pubkey [32]byte
 type Signature [64]byte
 func (id EventID) IsZero() bool { return id == EventID{} }
 func (id EventID) Hex() string  { return hex.Enc(id[:]) }
 ```
 **Benefit:** Stack allocation for local variables, zero-value comparison efficiency.
 ### 3. Pre-allocated Slice Patterns
 **Current usage is good:**
 ```go
 // pkg/database/save-event.go:51-54
 sers = make(types.Uint40s, 0, len(idxs)*100) // Estimate 100 serials per index
 // pkg/database/compact_event.go:283
 ev.Tags = tag.NewSWithCap(int(nTags)) // Pre-allocate tag slice
 ```
 **Improvement:** Apply consistently to:
 - `Uint40s.Union/Intersection/Difference` methods (currently use `append` without capacity hints)
 - Query result accumulation in `query-events.go`
 ### 4. Escape Analysis Optimization
 **Priority: Medium**
 Several patterns cause unnecessary heap escapes. Check with:
 ```bash
 go build -gcflags="-m -m" ./pkg/database/...
 ```
 **Common escape causes in codebase:**
 ```go
 // compact_event.go:224 - Small slice escapes
 buf := make([]byte, 5)  // Could be [5]byte on stack
 // compact_event.go:335 - Single-byte slice escapes
 typeBuf := make([]byte, 1)  // Could be var typeBuf [1]byte
 ```
 **Fix:**
 ```go
 func readUint40(r io.Reader) (value uint64, err error) {
    var buf [5]byte  // Stack-allocated
    if _, err = io.ReadFull(r, buf[:]); err != nil {
        return 0, err
    }
    // ...
 }
 ```
 ### 5. Atomic Bytes Wrapper Optimization
 **Location**: `pkg/utils/atomic/bytes.go`
 Current implementation copies on both Load and Store:
 ```go
 func (x *Bytes) Load() (b []byte) {
    vb := x.v.Load().([]byte)
    b = make([]byte, len(vb))  // Allocation on every Load
    copy(b, vb)
    return
 }
 ```
 This is safe but expensive for high-frequency access. Consider:
 - Read-copy-update (RCU) pattern for read-heavy workloads
 - `sync.RWMutex` with direct access for controlled use cases
 ### 6. Goroutine Management
 **Current patterns:**
 - Worker goroutines for message processing (`app/listener.go`)
 - Background cleanup goroutines (`querycache/event_cache.go`)
 - Pinger goroutines per connection (`app/handle-websocket.go`)
 **Assessment:** Good use of bounded channels and `sync.WaitGroup` for lifecycle management.
 **Improvement:** Consider a worker pool for subscription handlers to limit peak goroutine count:
 ```go
 type WorkerPool struct {
    jobs    chan func()
    workers int
    wg      sync.WaitGroup
 }
 ```
 ---
 ## Memory Budget Analysis
 ### Runtime Memory Breakdown
 | Component | Estimated Size | Notes |
 |-----------|---------------|-------|
 | Serial Cache (pubkeys) | 3.2 MB | 100k × 32 bytes |
 | Serial Cache (event IDs) | 16 MB | 500k × 32 bytes |
 | Query Cache | 512 MB | Configurable, compressed |
 | Per-connection state | ~10 KB | Channels, buffers, maps |
 | Badger DB caches | Variable | Controlled by Badger config |
 ### GC Tuning Recommendations
 For a relay handling 1000+ events/second:
 ```go
 // main.go or init
 import "runtime/debug"
 func init() {
    // More aggressive GC to limit heap growth
    debug.SetGCPercent(50)  // GC at 50% heap growth (default 100)
    // Set soft memory limit based on available RAM
    debug.SetMemoryLimit(2 << 30)  // 2GB limit
 }
 ```
 Or via environment:
 ```bash
 GOGC=50 GOMEMLIMIT=2GiB ./orly
 ```
 ---
 ## Profiling Commands
 ### Heap Profile
 ```bash
 # Enable pprof (already supported)
 ORLY_PPROF_HTTP=true ./orly
 # Capture heap profile
 go tool pprof http://localhost:6060/debug/pprof/heap
 # Analyze allocations
 go tool pprof -alloc_space heap.prof
 go tool pprof -inuse_space heap.prof
 ```
 ### Escape Analysis
 ```bash
 # Check which variables escape to heap
 go build -gcflags="-m -m" ./pkg/database/... 2>&1 | grep "escapes to heap"
 ```
 ### Allocation Benchmarks
 Add to existing benchmarks:
 ```go
 func BenchmarkCompactMarshal(b *testing.B) {
    b.ReportAllocs()
    ev := createTestEvent()
    resolver := &testResolver{}
    b.ResetTimer()
    for i := 0; i < b.N; i++ {
        data, _ := MarshalCompactEvent(ev, resolver)
        _ = data
    }
 }
 ```
 ---
 ## Implementation Priority
 1. **High Priority (Immediate Impact)**
   - Implement `sync.Pool` for `bytes.Buffer` in serialization paths
   - Replace small `make([]byte, n)` with fixed arrays in decode functions
 2. **Medium Priority (Significant Improvement)**
   - Add pre-allocation hints to set operation methods
   - Optimize escape behavior in compact event encoding
   - Consider worker pool for subscription handlers
 3. **Low Priority (Refinement)**
   - LRU-based serial cache eviction
   - Fixed-size types for cryptographic values (requires nostr library changes)
   - RCU pattern for atomic bytes in high-frequency paths
 ---
 ## Conclusion
 ORLY demonstrates thoughtful memory optimization in its storage layer, particularly the compact event format achieving 87% space savings. The dual-cache architecture (serial cache + query cache) balances memory usage with lookup performance.
 The primary opportunity for improvement is in the serialization hot path, where buffer pooling could significantly reduce GC pressure. The recommended `sync.Pool` implementation would have immediate benefits for high-throughput deployments without requiring architectural changes.
 Secondary improvements around escape analysis and fixed-size types would provide incremental gains and should be prioritized based on profiling data from production workloads.
