Clients has been running Smartlists for years. They have accumulated over 1,000,000 records in the SOP30300 table. Running the unfiltered sales line detail Smartlist will take over 3 minutes before any records are displayed. If I go to SSMS and run SELECT TOP 1000 FROM [dbo].[SOP30300] the records display almost immediately. What could be causing this difference in GP with the Smartlist?
