Just upgraded my son's eMac 1.25Ghz (OS X.3.9) model with 512MB RAM for a total of 768MB. I thought this would make the computer more 'zippy', but to my disappointment it didn't. Is there any way to speed up the computer? I feel that I should be able to control the VM ala OS 9 by shutting it off or turning back on. In OS 9 I NEVER ran VM, now I am and it just makes me wait. Love OS X but the memory management sucks. Call me old fashion but at least in OS 9 things were fast.
