[check-licenses] Add -trace and -pprof Add a few trace.Region() to better understand in which section the time is most spent, coupled with the flame graph this gives a pretty good overview of what's happening. Ran: fx check-licenses -trace trace.out -pprof profile.out or (faster): cd tools go run ./check-licenses/cmd \ -base_dir .. \ -config_file check-licenses/config/config.json \ -license_pattern_dir check-licenses/golden/patterns/ \ -trace trace.out \ -pprof profile.out then go tool trace trace.out go tool pprof profile.out It used to have more than 8 million (!) goroutines started before I started refactoring.
