Golang : Measure http.Get() execution time
There are times where you need to measure how long a http.Get() response time takes for debugging reason or network optimization purpose. It is kinda like ping command and in this tutorial, we will learn how to implement the code in Golang to measure the time taken for http.Get().
Here you go :
package main
import (
"fmt"
"os"
"time"
"net/http"
)
func main() {
start := time.Now()
url := "http://www.golang.org"
result, err := http.Get(url)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
defer result.Body.Close()
elapsed := time.Since(start).Seconds()
fmt.Printf("http.Get to %s took %v seconds \n", url, elapsed)
}
Sample output :
http.Get to http://www.golang.org took 1.227666872 seconds
