(This is not a specific RadGrid issue, but I need to place it somewhere...)

We are having bad performance in some parts of our webapp, based on RadControls and UpdatePanels. It is mainly client rendering that takes time.
I've read lots of post here and elsewhere about turning client-features off etc, but what I would really like to do is to figure out what takes so long on the client. For instance, entering edit mode in a RadGrid with ~20 rows and 10 columns takes 10-15 seconds in IE6/7.
With IE8 and FF3 there are good profilers, but the performance problem is not nearly as bad in these browsers, and we need to target IE6/7. For these versions of IE, I haven't found any good performance tuning tool. I guess I could instrument the ajax .js-files manually, as well ad RadControls .js-files, but that would be really awkward to do, since I don't know where the bottleneck is.

So, my question is: Does anyone have any good recommendation on techniques to tune performance for client-side rendering (especially where UpdatePanels are used)?

Thanks!
