Setting GroupingView to grid increases update time of grid to some degree
I have instance of Grid with 50 rows and 7 columns.
On pressing button all rows of grid are updating by following calling: gridStore.update( testGridNode );
For grid without grouping view update takes about 0.6 second.
Update of Grouping Grid takes about 3.4 seconds!
Simple test case is attached.
The questions are:
Is there way to improve it?
May be is there way of multiple update, like multiple add ( method that receives list of models )?
Is something planned for next release for improving this bad update performance?
We are using Ext GWT 2.2.4.
Thank you for your response.
Still I think grouping grid view is useful view and hope is popular enough so it should have better update performance.
Our real case is following: we have grouping grid with 100-150 rows, 7 columns, about 1-5 groups, one or more properties of row model are changed in about 70% of all rows each 1-2 seconds. Removing and adding all rows again is not suitable for us. But probably we can try to disable grouping while performing updates. Can you please advise how to do it?
