I have a relatively large music library at about 120 gigs. When I play my library on random, after an hour or so my machine has well +50,000 pageouts. This has occurred on both of my recent machines with 8 gigs of memory. I found if I load activity monitor and begin to skip ahead in tracks, I can watch the iTunes memory skyrocket from an initial 95 megs to 200+. Has anyone else run into similar issues or can anyone with a large library duplicate this?
