So I've been working on my iTunes library over the last couple days, adding music, album art, etc... So I decided to go see how much RAM I had available (just because I like to make sure I don't have run-away processes and such) when I noticed that I had very little Real RAM available... looking down my list, I noticed that the process taking the most RAM was none other than iTunes! Check this out: For reference, I included my WindowServ. My uptime is 3 days, 4 hours, 20 minutes. Pretty shocking, huh?
