[CLOSED] Issue with huge grid

[RRD]

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...895#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.

[RRD]

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.
