I'm a firm believer in never putting more records in a grid than the user will be able to comprehend. I'm in process of upsizing a VFP system (not my original design) that has the same problem.

My approach is to set up filtering criteria (the WHERE clause) before the data is selected and before the grid is displayed.

Restrict by date range, client name, or something that will immediately bring the dataset down to a manageable size and speed. THEN show the grid.
