Ok so i finally made the jump and upgraded to Leopard. It was a clean install, didn't go the "upgrade" route. I'm really enjoying a lot of the new features like spaces, time machine, and bootcamp but everything just seems to run so much slower than it did on Tiger. It just seems like such a memory hog. Is this lag normal? I was using parallels on tiger and it ran great, now I'm on a trial of vm ware fusion and it just keeps hanging. I thought maybe it was just the program itself, but i'm noticing that having too many things open now really affects it. For instance, having adium, safari, & itunes open at the same time, my system will beachball for about 10 -15 seconds. I've maxed out my memory (2gb) and have a 320gb 5400 hdd. Any ideas?
