Just for fun, on a core2duo make allnoconfig make -j8 here are the build time differences (on a 1000HZ config) machine: 16ms: 53.68user 4.81system 0:34.27elapsed 170%CPU (0avgtext+0avgdata 0maxresident)k 1ms: 56.73user 4.83system 0:36.03elapsed 170%CPU (0avgtext+0avgdata 0maxresident)k 5000ms: 52.88user 4.77system 0:32.37elapsed 178%CPU (0avgtext+0avgdata 0maxresident)k For the record, 16ms is what SD v0.43 would choose as the default value on this hardware. A load with a much lower natural context switching rate than a kernel compile, as you said Nick, would show even greater discrepancy in these results. Fun eh? Note these are not for any comparison with anything else; just to show the effect rr_interval changes have on throughput. -- -ck - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
