You actually snipped the line I was querying. I was not talking about the load averages, but the actual percentage of load which is credited to 'system': CPU states: 22.0% user, 0.0% nice, 55.1% system, 0.9% interrupt, 22.0% idle This does seem excessively high to me. > As for top, you'd expect it to measure its own CPU usage during the > period in which it is sampling, since it is actually running during that > time. It doesn't mean that it's using a constant 27% of your CPU. I understand that, but even on my P75 -current pentium system, top only accounts for 5% cpu load while running the same test.
