Measure website response time through curl

In this article I will show you how you can get the response time of any damn website.I am going to use curl for that purpose.As we know curl is extremly powerful to fetch lot many thing.I got this idea from one of IBM DW article and wrote a script to do just that for me.So here is the script I write:


1 #!/bin/bash
2 CURL="/usr/bin/curl"
3 GAWK="/usr/bin/gawk"
4 echo -n "Please pass the url you want to measure: "
5 read url
6 URL="$url"
7 result=`$CURL -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total} $URL`
8 echo " Time_Connect Time_startTransfer Time_total "
9 echo $result | $GAWK -F: '{ print $1" "$2" "$3}'


This is very ordinary script but it does the job it was intended to do.Here is the interaction with script below:

bhaskar@bhaskar-laptop_09:02:55_Fri Nov 12:/lvm/Adm_scripts> sudo ./measure_website_response
Please pass the url you want to measure: http://justlinux.com
Time_Connect Time_startTransfer Time_total
1.122 3.455 9.205


Hope this will help.

Cheers!
