Asp.Net slow with IE 11

I have an Asp.Net 4.5 web application. Since we migrated to IE 11 we have the following performance issue: Whenever I click on a button, the button stays selected for nearly two seconds and then the request is executed. This does not happen with IE 10 or Firefox. Is there any IE 11 specific configuration I have to consider?

I profiled the application with ants profiler, with Internet Explorer's developer tools and Visual Studio debugger. I did not find anything special on java script side nor on server side. We are using DevExpress controls and a little bit of jQuery.

I know that I am very general, but we have no idea, what the problem could be.

After removing all java script, jquery etc, the problem did not disappear. So we investigated more into the page itself. The reason for performance problems was an update panel we used. Adding the workaround from

fixed the problem immediately.

There is nothing in ASP.NET per se that would be causing your issues. There has to be something wrong in the JavaScript is my guess. It could either be your code or DevExpress code. Do a memory profile, take a snapshot. Are there any memory leaks? Run the script profiler see what is hogging the CPU, etc. If I were you I would focus on your code and see if anything there is the issue because you can control it. If you cant find anything there check the DevExpress forums, etc.
