Javascript Performance Measurement in IE

I have a webpage that uses Javascript to a large extent (AJAX requests, Google Maps APIs, HTML building, etc.), and the page brings my computer to its knees whenever it opens in Internet Explorer. I'm looking for some tools to help me find out which features take the most time. I have some basic javascript functions for profiling, but this does not help, given that I do not know which function is especially slow. The tool should be for IE, since the page works fine in other browsers.

In fact, you can check out the developer tools that come with IE8. I know js debugging and profiling are part of this.
