Measure Exection time in Go
To know who how long your go code executes you can use the
time.Now() and time.Since() methods in the time package.Demo
1
package main
2
3
import (
4
"fmt"
5
"time"
6
)
7
8
func main(){
9
10
start := time.Now()
11
dur, _ := time.ParseDuration("15ms")
12
13
// A Go Anonymous function (self-executing)
14
func (){
15
for i := 0; i < 100; i++ {
16
time.Sleep(dur)
17
fmt.Println("Bhupesh is programming in Go")
18
}
19
}()
20
21
elapsed := time.Since(start)
22
23
fmt.Printf("Execution Time : %s", elapsed)
24
}

Since() returns the time elapsed since t (
start in our demo). It is shorthand for time.Now().Sub(t).1
