last pid: 11406; load averages: 0.07, 0.02, 0.00 up 2+20:54:15 15:36:35 23 processes: 1 running, 22 sleeping CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 0.0% idle That is what it is displaying, the load adverage isnt it, its just the CPU stats. It always displays 0.0% all the way across the board with the machine idle or doing any kind of work.
