SQL Server will dynamically grab and release memory as it sees fit. It will release memory if it sees that there are other processes on the server that need memory. Have you tried to set SQL Server's memory to a fix value? Use the server options dialog in the SEM and fix the memory at something like 1GB and then rerun your tests.

>It's definitely SQL Server. It seems like SQL is caching the table data in RAM but never freeing up the memory again. I haven't found anythng related to my problem at MS but am still looking.

I've had a few more knowledgable database people tell me that SQL NEVER gives up the memory and that every SQL server needs to be rebooted periodically - is this true?
