Reassigning to PM since this is a feature request. Hello, Allen. It looks to me like the cpu usage %'s are correct, although obviously the system-wide totals have a factor of 4 figured in (on a 4-cpu system). In your 1st set of results, you have: (0.0 + 69.0 + 0.0 + 31.5) / 4 = 25.1 There is obviously some minor variation from one instant to the next (from when "top" runs to when "ps" runs). And the fact that process timing is done in 1/HZ intervals is by design (in order to have low overhead). |
