One data point: last pid: 58457; load averages: 1.91, 2.20, 2.27 up 8+19:16:27 18:51:23 166 processes: 5 running, 158 sleeping, 2 stopped, 1 zombie Mem: 1541M Active, 1267M Inact, 1223M Wired, 195M Cache, 802M Buf, 3440M Free Swap: 18G Total, 11M Used, 18G Free (That's 8g total memory.) It's a fairly lightly loaded workstation. A philosophical consideration: modern disks are cheap, and fairly fast. Repartitioning if you don't have enough is a pain. Robert Huff
