You never optimize without profiling first ā€” measure, hypothesize, change one thing, re-measure.\n\n**Thinking mode:** Reason as thoroughly as possible for performance optimization ā€” shallow analysis misidentifies bottlenecks and deep reasoning ensures the right optimization is applied to the right problem. On Claude Code, use `ultrathink` to trigger extended thinking explicitly.\n\n**Orchestration mode:** Fan out the three sub-agents described in Review mode (architecture) (allocation and memory layout, I/O and concurrency, algorithmic complexity and caching) for a broad architectural performance review. A single hot-path review stays sequential; fan-out only pays off at package/service scope. On Claude Code, use `ultracode` to opt into multi-agent orchestration explicitly.\n\n**Modes:**\n\n- **Review mode (architecture)** ā€” broad scan of a package or service for structural anti-patterns (missing connection pools, unbounded goroutines, wrong data structures). Use up to 3 parallel sub-agents split by concern: (1) allocation and memory layout, (2) I/O and concurrency, (3) algorithmic complexity and caching.\n- **Review mode (hot path)** ā€” focused analysis of a single function or tight loop identified by the caller. Work sequentially; one sub-agent is sufficient.\n- **Optimize mode** ā€” a bottleneck has been identified by profiling. Follow the iterative cycle (define metric ā†’ baseline ā†’ diagnose ā†’ improve ā†’ compare) sequentially ā€” one change at a time is the discipline.\n\n**Dependencies:**\n\n- benchstat: `go install golang.org/x/perf/cmd/benchstat@latest`\n\n# Go Performance Optimization\n\n## Core Philosophy\n\n1. **Profile before optimizing** ā€” intuition about bottlenecks is wrong ~80% of the time. Use pprof to find actual hot spots (ā†’ See `samber/cc-skills-golang@golang-troubleshooting` skill)\n2. **Allocation reduction yields the biggest ROI** ā€” Go's GC is fast but not free. Reducing allocations per request often matters more than micro-optimizing CPU\n3. **Document optimizations** ā€” add code comments explaining why a pattern is faster, with benchmark numbers when available. Future readers need context to avoid reverting an \"unnecessary\" optimization\n\n## Rule Out External Bottlenecks First\n\nBefore optimizing Go code, verify the bottleneck is in your process ā€” if 90% of latency is a slow DB query or API call, reducing allocations won't help.\n\n**Diagnose:** 1- `fgprof` ā€” captures on-CPU and off-CPU (I/O wait) time; if off-CPU dominates, the bottleneck is external 2- `go tool pprof` (goroutine profile) ā€” many goroutines blocked in `net.(*conn).Read` or `database/sql` = external wait 3- Distributed tracing (OpenTelemetry) ā€” span breakdown shows which upstream is slow\n\n**When external:** optimize that component instead ā€” query tuning, caching, connection pools, circuit breakers (ā†’ See `samber/cc-skills-golang@golang-database` skill, [Caching Patterns](references/caching.md)).\n\n## Iterative Optimization Methodology\n\n### The cycle: Define Goals ā†’ Benchmark ā†’ Diagnose ā†’ Improve ā†’ Benchmark\n\n1. **Define your metric** ā€” latency, throughput, memory, or CPU? Without a target, optimizations are random\n2. **Write an atomic benchmark** ā€” isolate one function per benchmark to avoid result contamination (ā†’ See `samber/cc-skills-golang@golang-benchmark` skill)\n3. **Measure baseline** ā€” `go test -bench=BenchmarkMyFunc -benchmem -count=6 ./pkg/... | tee /tmp/report-1.txt`\n4. **Diagnose** ā€” use the **Diagnose** lines in each deep-dive section to pick the right tool\n5. **Improve** ā€” apply ONE optimization at a time with an explanatory comment\n6. **Compare** ā€” `benchstat /tmp/report-1.txt /tmp/report-2.txt` to confirm statistical significance\n7. **Commit** ā€” paste the benchstat output in the commit body so reviewers and future readers see the exact improvement; follow the `perf(scope): summary` commit type\n8. **Repeat** ā€” increment report number, tackle next bottleneck\n\nRefer to library documentation for known patterns before inventing custom solutions. Keep all `/tmp/report-*.txt` files as an audit trail.\n\nWhen multiple candidate optimizations compete for the same bottleneck, implement each in an isolated worktree via a separate sub-agent ā€” then ā†’ See `samber/cc-skills-golang@golang-benchmark` skill for comparing the variants and its serial-measurement caveat (concurrent benchmark runs on shared CPU contaminate results, even when the implementations themselves were built in parallel).\n\n## Decision Tree: Where Is Time Spent?\n\n| Bottleneck | Signal (from pprof) | Action |\n| --- | --- | --- |\n| Too many allocations | `alloc_objects` high in heap profile | [Memory optimization](references/memory.md) |\n| CPU-bound hot loop | function dominates CPU profile | [CPU optimization](references/cpu.md) |\n| GC pauses / OOM | high GC%, container limits | [Runtime tuning](references/runtime.md) |\n| Network / I/O latency | goroutines blocked on I/O | [I/O & networking](references/io-networking.md) |\n| Repeated expensive work | same computation/fetch multiple times | [Caching patterns](references/caching.md) |\n| Wrong algorithm | O(nĀ²) where O(n) exists | [Algorithmic complexity](references/caching.md#algorithmic-complexity) |\n| Lock contention | mutex/block profile hot | ā†’ See `samber/cc-skills-golang@golang-concurrency` skill |\n| Slow queries | DB time dominates traces | ā†’ See `samber/cc-skills-golang@golang-database` skill |\n\n## Common Mistakes\n\n| Mistake | Fix |\n| --- | --- |\n| Optimizing without profiling | Profile with pprof first ā€” intuition is wrong ~80% of the time |\n| Default `http.Client` without Transport | `MaxIdleConnsPerHost` defaults to 2; set to match your concurrency level |\n| Logging in hot loops | Log calls prevent inlining and allocate even when the level is disabled. Use `slog.LogAttrs` |\n| `panic`/`recover` as control flow | panic allocates a stack trace and unwinds the stack; use error returns |\n| `unsafe` without benchmark proof | Only justified when profiling shows >10% improvement in a verified hot path |\n| No GC tuning in containers | Set `GOMEMLIMIT` to 80-90% of container memory to prevent OOM kills |\n| `reflect.DeepEqual` in production | 50-200x slower than typed comparison; use `slices.Equal`, `maps.Equal`, `bytes.Equal` |\n\n## Deep Dives\n\n- [Memory Optimization](references/memory.md) ā€” allocation patterns, backing array leaks, sync.Pool, struct alignment\n- [CPU Optimization](references/cpu.md) ā€” inlining, cache locality, false sharing, ILP, reflection avoidance\n- [I/O & Networking](references/io-networking.md) ā€” HTTP transport config, streaming, JSON performance, cgo, batch operations\n- [Runtime Tuning](references/runtime.md) ā€” GOGC, GOMEMLIMIT, GC diagnostics, GOMAXPROCS, PGO\n- [Caching Patterns](references/caching.md) ā€” algorithmic complexity, compiled patterns, singleflight, work avoidance\n- [Production Observability](references/observability.md) ā€” Prometheus metrics, PromQL queries, continuous profiling, alerting rules\n\n## CI Regression Detection\n\nAutomate benchmark comparison in CI to catch regressions before they reach production. ā†’ See `samber/cc-skills-golang@golang-benchmark` skill for `benchdiff` and `cob` setup.\n\n## Cross-References\n\n- ā†’ See `samber/cc-skills-golang@golang-benchmark` skill for benchmarking methodology, `benchstat`, and `b.Loop()` (Go 1.24+)\n- ā†’ See `samber/cc-skills-golang@golang-troubleshooting` skill for pprof workflow, escape analysis diagnostics, and performance debugging\n- ā†’ See `samber/cc-skills-golang@golang-data-structures` skill for slice/map preallocation and `strings.Builder`\n- ā†’ See `samber/cc-skills-golang@golang-concurrency` skill for worker pools, `sync.Pool` API, goroutine lifecycle, and lock contention\n- ā†’ See `samber/cc-skills-golang@golang-safety` skill for defer in loops, slice backing array aliasing\n- ā†’ See `samber/cc-skills-golang@golang-database` skill for connection pool tuning and batch processing\n- ā†’ See `samber/cc-skills-golang@golang-observability` skill for continuous profiling in production\n","tagline":"Golang performance optimization patterns and methodology - if X bottleneck, then apply Y.
