At any HZ the ratio should be around 1:10 > (+- rounding error). you are wrong again. I sent you the numbers earlier today already: | PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND | 2332 mingo 25 0 1580 248 196 R 95.1 0.0 0:11.84 loop | 2335 mingo 39 19 1576 244 196 R 3.1 0.0 0:00.39 loop 3.1% is 3067% more than 95.1%, and the ratio is 1:30.67. You again deny above that this is the case, and there's nothing i can do about your denial of facts - that is your own private problem. Ingo
