Sysbench thinks SD_BALANCE_WAKE is too agressive and kbuild doesn't really mind too much, SD_BALANCE_NEWIDLE picks up most of the slack. On a dual socket, quad core, dual thread nehalem system: sysbench (--num_threads=16): SD_BALANCE_WAKE-: 13982 tx/s SD_BALANCE_WAKE+: 15688 tx/s kbuild (-j16): SD_BALANCE_WAKE-: 47.648295846 seconds time elapsed ( +- 0.312% ) SD_BALANCE_WAKE+: 47.608607360 seconds time elapsed ( +- 0.026% ) (same within noise) Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
