No downloading. It's using the same virtual memory now, 358 MB, plus 83.5 MB ram
I have 2 GB ram and 1.5 GB of that is free, so it may be the way Tiger manages memory. I would rather see all my ram used. I paid extra for that.
TextEdit is using over 230 MB swap, the SystemUI Server , Preview, Little Snitch firewall, Growl, Finder, Dock and the Activity Monitor all use about the same. I have 4.6 GB swap open. I opened OpenOffice 2.4 and the swap went up to 5.6 GB.
Inspecting the process says Real memory 82MB (43.5 shared and 52.5 private), 350MB virtual, and 82.5 VPM. The cpu use floats from about 9% to 50% when opening a new blank window. 12 threads and 290 ports.
