When all 3 seti's get their "normal" 95% cpu time:
32531 setiathome 139 15 16536K 15520K *Giant 1 60.9H 95.85% 95.85% setiathome
32533 setiathome 139 15 16856K 16032K CPU3 3 61.0H 95.65% 95.65% setiathome
32532 setiathome 139 15 15524K 14912K CPU2 2 60.8H 95.51% 95.51% setiathome
54738 andyf 132 0 3084K 2140K *Giant 0 64:54 83.84% 83.84% ssh
12 root -16 0 0K 12K RUN 2 133.4H 3.81% 3.81% idle: cpu2
13 root -16 0 0K 12K RUN 1 131.7H 3.47% 3.47% idle: cpu1
14 root -16 0 0K 12K CPU0 0 130.8H 3.37% 3.37% idle: cpu0
11 root -16 0 0K 12K RUN 3 135.2H 2.88% 2.88% idle: cpu3
As opposed to "abnormal" when cpu_idle_hlt=1:
32533 setiathome 139 15 15828K 15000K CPU1 2 61.0H 89.40% 89.40% setiathome
32532 setiathome 139 15 16552K 15660K *Giant 2 60.8H 88.18% 88.18% setiathome
54738 andyf 130 0 3084K 2140K select 2 68:54 75.78% 75.78% ssh
13 root -16 0 0K 12K RUN 1 131.7H 29.05% 29.05% idle: cpu1
12 root -16 0 0K 12K CPU2 2 133.4H 28.08% 28.08% idle: cpu2
11 root -16 0 0K 12K CPU3 3 135.2H 27.83% 27.83% idle: cpu3
14 root -16 0 0K 12K RUN 0 130.8H 26.37% 26.37% idle: cpu0
32531 setiathome 131 15 15640K 14976K *Giant 2 61.0H 20.51% 20.51% setiathome
