HELP! Okay, first, I have a very solid background in computing, and I've been somewhat of a hacker using windows systems since I was twelve. I can do just about anything on my XP system, but the Mac world is pretty new to me. My other half uses the MacBook Pro we have much more often than I do, mainly for Lightroom, Firefox, and Photoshop, and on that I can guarantee it performs much better. I still need Windows for games though. Anyway, it's been slowing down recently. At first, we thought it was overheating (he likes to leave it on for days at a time, just sleeping, a crime, I know) so he shut it off for a full day. Still slower. So I went into activity monitor, and looked at the mem usage. Now, I've seen some crazy things. I had a game in 2000 that would use a quarter of a gig of ram, and another half of virtual, but this? THIS IS INSANITY! -http://www.imagebanana.com/view/1ok2piob/Picture3.png The virtual mem usage for firefox is expected (He HOARDS tabs) but everything else is downright retarded. Anyway, my question is: why is this happening, it's never before, and how can I fix it?
