You might find the the idle process > for CPU0. Is this what you want: $ ps -auxw | grep idle root 11 99.0 0.0 0 8 ?? RL 7:45PM 0:00.00 [idle: cpu1] root 12 0.0 0.0 0 8 ?? RL 7:45PM 51:04.57 [idle: cpu0] I'm sure it could be a top issue, but other tools that don't use top report only 50% total cpu usage..
