What's at the link might help you. OTOH, do NOT switch VM off, under any circumstances. It won't make anything run faster, some programs need VM to work, and you may experience... right, slowdowns. :-) I don't say the system slowed down because you turned VM off, but it might certainly be that. Also, if you have any memory manager running, uninstall it.
