Measuring Javascript performance in IE

Question

Hi everyone,

I have a webpage that heavily uses Javascript (AJAX requests, Google Maps API, HTML building, etc) and the page brings my PC to its knees whenever opened in Internet Explorer. I'm looking for some tools to help me find out which functions are taking the most time to finish. I have some basic profiling javascript functions, but those don't help much considering I don't know what function specifically is being slow. The tool has to be for IE, as the page runs fine in other browsers.

Answer 1

You might actually want to check out the Developer tools that come with IE8. I know js debugging and profiling are part of it.

Answer 2

Take a look at YUI Profiler.

Answer 3

For JavaScript, XmlHttpRequest, DOM Access, Rendering Times and Network traffic for IE6, 7 & 8 you can use the free dynaTrace AJAX Edition
