View Full Version : [4.0.1] Grid performance still too slow

Have a grid with 9 columns, forceFit true, in a nested BorderLayout, buffered store.

In IE9 strict, the browser locks up for about 3-4 seconds between the time the grid panel is unmasked and the time the scroller appears.

In IE8, the lock up is 5-7 seconds.

In Chrome, it's 1/2 second or less (which is what I would expect).

It's an improvement, but it has a long way to go.

A screen shot of a profiler run for IE9 is attached, if at all helpful.

To the Sencha team: There's no way I can package up my app to demo this practically. I would be happy to demonstrate in a GoToMeeting if that works for you.

Cheers,

stevil

Hello,

I think I have the same problem if you want an example:
