This is probably not the right section for this question. but I could not find any other that looked appropriate.

I have a client who is running my VFP app (native VFP data) though citrix on a Windows Server 2003 box.

Ever since the last security update ( as nearly as we can pinpoint it ), my app is CRAWLING when it is doing intensive data I/O operations ( processing and building dbf’s that can be up to ½ GB ).

The exact same operations that take 15 minutes on my XP box are taking over an hour on his server.

Are there any known issues? Any workarounds?

Thanks!
