i recently installed shapeshifter to my new iMAC 20 inch core 2 duo, and i've noticed programs take a little longer to open and performance has been a little slower; has anyone else noticed this? is it supposed to be a big RAM eater? any way of finding out what programs are running in background or what processes are running in background that i can terminate or which are eating up lots of ram? the problem is tolerable it's just annoying; i remember in the past opening a program was almost instantanous but now the icon jumps for 3-4 times before it launches. mabe it's time to buy more ram, i thought 1 gig was plenty.
