Golang : calculate elapsed run time
Calculating elapsed time can be useful for profiling or bench marking purpose. In this short tutorial, we will learn how to do simple elapsed time calculation in Go.
Basically, Golang's time.Since()
function should be sufficient :
start := time.Now() // get current time
// do something here
elapsed := time.Since(start)
and here is the full codes below demonstrate how to find out the the elapsed time :
package main
import (
"fmt"
"time"
)
func main() {
start := time.Now() // get current time
// some function
fmt.Println("Hello World!")
elapsed := time.Since(start)
fmt.Printf("Print Hello World took %s\n", elapsed)
}
Output(sample) :
Hello World!
Print Hello World took 46.445us
