ie7 ajax性能

Are there any tools to measure performance (similar to FireBug > Net tab (FireBugLite = no net tab)) that work in IE7?

I am having some serious lag come up in loading up screens. The issue seems to occur only within IE7. The site uses quite a bit of javascript/ajax (jQuery). I hear that IE7 has a poor JavaScript engine. Is this true? I mean, are there any known bugs, defined performance issues in jQuery API or otherwise "checkoutHowMuchIE7SucksComparedtoFF.Metrics.Ajax" dot com?

    This will give you an idea of javascript engine performance across browsers (it lists IE8 not 7, but I believe 7&8 use the same javascript engine[someone correct me if I'm wrong])

    Personally I use this technique to set up debugging in IE, without some code samples this is all I can suggest.
