Scheduler full update slow in IE 10

We are evalutating the latest MVC scheduler and are having trouble with performance when it comes to Internet Explorer 10. We are testing with 159 resources and 159 events and the initial load is quite fast. But when we click on the resource header to sort resources a full update is performed. It takes 10 to 15 seconds to reload the scheduler. If we try the same thing in Firefox it completes in 4 seconds. It has nothing to do with the data retrieval. Any suggestions?
