How slow can you go? If I load up my system with major apps, I see the load go up to about 15 or so while apps are loading, then drop down to 2 or 3 after all are loaded. Why load so much? I like to see load below 1.00 iTunes is first app that I quit when I see a high load. Plus, I've got 1 GB RAM. Very seldom have any pageouts, even with Classic apps in use. That's maybe the biggest indicator on your screen that shows you could use more than 320 MB RAM
