Execution Tracing in Go

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.

How to use

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
