Hi Guys,
First I developed Access-only solution (both back-end and front-end separately). Then I decided to upsize back-end to SQL server. I used upsize manager to migrate both structures and data and it went easily. Then I decided to recreate most of querries I use in SQL server, it took me some time but after all I was happy with the performance increased. Lately I've noticed huge performance drop when processing data added after the upsizing - original data process in no time, new data process in about 4-5 seconds without any reason I see. The querry I'm talking about selects projects wanted by user and and all project steps of the project. Number of records processed/pulled from SQL server is equal (about 100-120 records). It doesn't matter if I run the querry from Access (as push-through querry) or directly in SQL Server Management Studio - "original" data are processed in no time, new data in about 4-5 seconds. What might be going on? What should I check first?
Regards,
Robert
