I recently switched over from the old controls to the ASP.NET ones. What I'm seeing though is that the AJAX performance is much slower with the new ones.
I am using the RadAjaxManager to load portions of my page...sometimes large portions. In cases where I load a large portion of the page I see the page appear behind my loading panel, and then it takes about another 7 seconds (in IE) for the loading panel to go away and the client-side response end handler to get called.
The markup returns quickly and is rendered by the browser within 3 seconds, but what on Earth is going on the other 7 seconds is a mystery. I'm guessing that there is a bunch of client-side script running, but this is a reaaaally long delay. With the old RadAjaxManager it was much quicker.
Any suggestions around what I can do to debug it, and try to figure out why?
By the way, the delay is less than half in Firefox of what it is in IE.
Thanks,
Ross
