I've been dealing with a particularly slow running page which I've been attributing to issues with the queries. In IE 9 or 11 (with compatability view settings enabled) the report consistently runs for over 1 minute without completing.
I've tested the same page in Firefox and Chrome and found it runs in 15-20 seconds in it's worst case scenario (i.e. the most complicated set of prompts being used).
Has anyone encountered anything like this or do you have any ideas about what may be causing the problem in IE?
