#uptime 9:06AM up 6:14, 12 users, load averages: 25.39, 13.19, 9.55 I would think that CPU is under 100% when load=15.58 . But it is not: #top -S last pid: 17095; load averages: 13.26, 11.20, 8.57 up 0+06:12:25 09:04:27 514 processes: 3 running, 490 sleeping, 1 zombie, 20 waiting CPU states: 16.1% user, 0.0% nice, 1.8% system, 0.0% interrupt, 82.1% idle Mem: 1406M Active, 272M Inact, 247M Wired, 70M Cache, 112M Buf, 8380K Free Swap: 4096M Total, 4096M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 11 root 1 171 52 0K 8K RUN 0 214:21 43.70% idle: cpu0 10 root 1 171 52 0K 8K RUN 1 282:08 34.28% idle: cpu1 21 root 1 -68 -187 0K 8K WAIT 1 2:15 2.05% irq19: myk0 uhci3 16480 timea 1 97 0 34376K 17628K select 0 0:03 1.81% wnck-applet 14813 kornel 1 96 0 34376K 27384K select 0 0:20 1.12% skype 17095 root 1 96 0 3104K 2324K CPU1 1 0:00 1.00% top 16443 timea 1 96 0 17304K 12560K select 1 0:03 0.98% metacity 12 root 1 -44 -163 0K 8K WAIT 1 1:21 0.88% swi1: net 16550 timea 1 97 0 41760K 37284K select 0 0:15 0.73% wish8.4 2317 zsolt 1 96 0 29680K 22344K select 1 3:13 0.59% skype 3450 szgabor 1 96 0 28344K 21484K select 1 2:56 0.49% skype The most strange is that "last pid" is almost constant, about 1 process started per second. So how it is possible that "top -S" tells "82% idle" but "load" tells 15.58 ? Thanks, Laszlo
