Con Kolivas' patch has been included in test6. You might have tried that or maybe my patch? Anyway, lets just clarify your report: 1 CPU, hyperthreading on or off? test5 interactivity under load isn't as good as test6. povray takes 150% more time in test6 vs tset5. How many compute threads does povray use? Is anything else running? oowriter takes 3 seconds to load when nothing is running oowriter takes 30(or more) minutes to load when povray is runnnig, takes 1 minute in test5 plus patch (could you tell us exactly what the patch is) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
