fgprof is a sampling Go profiler that allows you to analyze On-CPU as well as Off-CPU (e.g. I/O) time together. Go's builtin sampling CPU profiler can only show On-CPU time, but it's better than fgprof at that. Go also includes tracing profilers that can analyze I/O, but they can't be combined with the CPU profiler. fgprof is designed for analyzing applications with mixed I/O and CPU workloads. This kind of profiling is also known as wall-clock profiling. Whilst fgprof can cause significant STW latencies in applications with a lot of goroutines (> 1-10k), these latencies only occur if the profile is requested - it doesn't cause a delay by simply being available. The fgprof profile is mounted on `http:https://localhost:6060/debug/fgprof?seconds=3` Signed-off-by: Andrew Thornton <[email protected]>
