I have 8GB of memory. Why do I have page outs and swap used? I have used iTunes, Mail, Chrome, Photoshop, and WoW since the last time I restarted my computer. I thought with 8GB of memory I would never see page outs or swap being used. One thing for sure is I've been watching Activity Manager since upgrading to 8GB just to see how much I would use, and I have always had at minimum 2.5GB free. I upgraded because I was tired of having high page outs and swap causing slow downs in WoW. WTF?
