I have a grid with about 1,000 records and then grouped - the largest group has about 580 records in it. When I click on the group heading to expand this group it is very slow (over 1 to 2 seconds). The grid has 16 columns in it. When I make the window smaller (i.e. only a smaller portion of the grid is visible) this reduces the time to expand the group.

Can you suggest any likely causes for this behavior and/or any ways to optimize it

Thanks

Hello Hamish,

Generally, I would suggest you to go through the Degraded Performance and the Tips and Tricks help articles suggesting on how you could improve the performance.

Let me know if any of the tips suggested there work for you
