By looking at your graph, that's around a 10% difference. So I'm not seeing anywhere near as bad a regression on a 80-core box. Testing single with 80 warehouses, I get: tip/master baseline: 677476.36 bops 705826.70 bops 704870.87 bops 681741.20 bops 707014.59 bops Avg: 695385.94 bops tip/master + patch (NUMA_SCALE/8 variant): 698242.66 bops 693873.18 bops 707852.28 bops 691785.96 bops 747206.03 bopsthis Avg: 707792.022 bops So both these are pretty similar, however, when reverting, on avg we increase the amount of bops a mere ~4%: tip/master + reverted: 778416.02 bops 702602.62 bops 712557.32 bops 713982.90 bops 783300.36 bops Avg: 738171.84 bops Are there perhaps any special specjbb options you are using? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
