This repo showcases how to use the pprof
and the trace
tools, built into the go binary, in order to take informed
decision on how to improve an application.
Uncomment the following lines inside the main.go
file in order to start profiling or tracing:
package main
func main() {
// Uncomment one at a time
// pprof.StartCPUProfile(os.Stdout)
// defer pprof.StopCPUProfile()
// trace.Start(os.Stdout)
// defer trace.Stop()
...
}
After doing that rebuild the binary and execute the following commands:
$ go build
$ time ./execution-tracing-in-go > t.out # for tracing
$ go tool trace t.out
