jquery/ js speed test

Question

I'm using lots of jquery/js in my website. I need to test my jquery performance and improve its performance. Is there any tools to monitor the jquery performance?

Answer 1

Firefox's Firebug has some pretty neat plugins for that:

• YUI slow
• Google Page Speed

Even if these plugins are very handy, you could measure the Javascript performance just with Firebug (Firefox) and the Developer Tools (Chrome).

Answer 2

You can use

Well explained here

YSlow

Firebug

To calculate your jQuery time in IE you can use

var startTime = new Date(); 
jQuery.ready(); 
var endTime = new Date(); 
var difference = endTime - startTime; 
alert("document.ready time: " + difference + " milliseconds");

with this code you could get time for jQuery to load
