View Full Version : Ext.grid.feature.GroupingSummary performance issue with 1000 row grid

10 May 2012, 11:30 AM
I have a grid with 20 columns, 1000 records and have the feature "Ext.grid.feature.GroupingSummary" turned on.

With the grouping feature added, a simple checkbox (xtype: 'checkcolumn') takes 6+ seconds to check/uncheck after a click event. I click the empty checkbox and have to wait 6 seconds before the check appears.

If I remove the grouping feature, the same click fires in < 1 second.

Is there a setting I can make on the GroupingSummary feature that will sped its performance on large grids?

I would expect this. 1000's rows is a lot! And... it's just a browser! How about using pagination?
