- Go's standard library includes pprof for profiling, but many developers avoid it due to complexity or lack of experience.
- Profiling helps identify CPU bottlenecks, memory issues, and concurrency problems to improve software performance.
- Main profile types in Go: CPU, heap, allocs, mutex, block, and goroutine, each sampling different data for analysis.
- Collect profiles via runtime/pprof for code control, net/http/pprof for services, or GoLand's profiler tool for ease.
- Inspect profiles using terminal commands, a web interface, or GoLand's integrated views like Top, Graph, Flame Graph, and Tree.
