go-performance-best-practices

Go performance optimization guidelines for profiling, allocation, GC tuning, concurrency, and I/O. This skill should be used when writing, reviewing, or optimizing Go code for performance. Triggers on tasks involving slow services, high latency, high memory usage, memory leaks, goroutine leaks, GC pressure, CPU profiling, pprof analysis, allocation reduction, sync.Pool, mutex contention, HTTP client tuning, or any Go performance investigation.

profiling-with-cpu-sampler

Time-based sampling profiler showing WHERE execution time is spent (wall-clock time, not frequency). Provides histogram with self/total time, compilation tiers (T0/T1/T2), and flame graphs. Use as FIRST step to identify hot functions consuming most time. Low overhead, suitable for longer runs. Pair with tracing-execution-counts to understand time-per-execution vs execution frequency.
