I have a system which has a reasonable large store (less than 1000 entries) and loads this store into a grid panel. On my mac running all browsers it runs fine and performs admirably (generally under 4 seconds to display the panel on screen).

However, when running on a Windows 8 machine using IE10 the exact same grid panel can take up to 30 minutes to render on screen instead of 3 or 4 seconds.

I have played around with store features such as the purgePageCount and PageSize with no success.

Just wondering if anyone else has suffered similar performance issues and can shed any light on how to improve the performance.

Thanks in advance for your help.
