Go profiling tools are absolutely excellent!

One more tool, which the OP surprisingly doesn't mention, is `go tool trace` for execution tracing. It's really useful, esp. when debugging GC behavior or CGO calls locking up threads.

Needlessly complicated for most CLI applications. A better starting point:

On this topic I highly recommend Bill Kennedy's talk: https://youtu.be/6qAfkJGWsns

It helped me to step upy profiling game quite a bit.
