I already searched for this but if it is here I apologize. Post a link if that is the case. When I was operating under Tiger my VM size was about 8-9 gig most of the time. Now I opened up activity monitor to see how much RAM my system was using under Leopard and I notice it is now up to about 34 gig. Is anyone else having this problem? Few applications running, no widgets. I have a gig and a half of real ram sitting there, I just don't know why half of my hard drive is VM.
