Hi,

I have a huge GridPanel with 259 columns and 92 rows with row expander. Extjs initial script consist of 733888 symbols. This script runs 35-40 seconds. Show or hide columns and expand row takes too long.
Could you give some advices how to optimize this?

As example you can use code from http://forums.ext.net/showthread.php?26597-Grid-issue&p=117895#post117895

Hi @RRD,

I am afraid there is no big chance to improve the performance. Just too many rows * columns.


35-40 seconds

I guess you are testing with IE, aren't you? It is much better in Chrome and FireFox. Though not appropriate anyway.

You are right. It was in IE 8. It's too slow. It is much better in Chrome, FireFox.

I am afraid there is no way to make a grid with a such amount of rows * columns working well in IE8.
