Service Desk Build 10501 Slow In Internet Explorer 11

Hi, 

After successfully upgrading our TEST environment to the most recent Service Build, I am noticing Service Desk is extremely slow in IE 11. 
This however is not a problem if using Google Chrome, its almost completely the opposite.

Any idea's on what could be causing the issue with IE? 

Thanks
