Understanding the Go Runtime: Profiling
Summary
The article dives into Go runtime profiling, detailing five profile types (CPU, heap, block, mutex, goroutine), the common pprof data format, and how each profile is collected. It explains the collection models behind CPU (signal-driven), heap (in-place), block/mutex (bucketed), and goroutine (on-demand) profiling, and discusses practical implications for performance analysis and Go development.
