Thanks a lot. How can I now find out, how much memory I'm using? I tried to use that setting and I don't see a speed difference.

I think, our problem is related to TEMP files. I think, our users don't have an access to Windows default temp files directory... That's my theory, which I hadn't chance to test yet.
