Hello! I just switched from an iBook G4 to an iMac G5 and I wanted to run something past the PPC people here to make sure I wasn't crazy or if the behavior I am seeing with the iMac is normal. When I was using my iBook G4 with 1.5GB RAM, I would usually have plenty of Memory available for numerous apps(those apps being Mail, WebKit, iTunes, Activity Monitor, Terminal, and TenFourFox). The problem I am seeing now is that the iMac G5(PowerMac 12,1, 1.9GHz, 1.5GB RAM, 633MHz bus speed with iSight, running OS X 10.5.8) doesn't seem to be as effective at memory management as the iBook. Inactive memory builds up more quickly and I am noticing page outs and have already used 16.02 MB of Swap. What I'm wondering is: Is this normal, and should I basically be looking for a more RAM. Thanks in advance for any insight and assistance.
