I've verified that the reverts improve netperf TCP_RR performance. Here I've got two Xeon's, slightly different, so I run in both directions. Also I run two ways -- Out-of-the-box, plus with cpufreq set to max frequency. The reverts improve all 4 cases: JKT → IVT IVT → JKT 3.11.0-rc2 baseline w/o revert Out of Box 20420 19963 20658 19915 20298 20320 3.11.0-rc2 baseline w/o revert max freq 59658 51427 59663 51503 59416 51343 3.11.0-rc2-00002-g74bce39 Linux-pm “fixes-next” branch 3.11.0-rc2-00002-g74bce39 Out of box 23227 22056 23306 22125 23387 40226 40k result saw some 2.2 ghz vs 1.2 ghz in other runs 21991 3.11.0-rc2-00002-g74bce39 Max-freq 67240 57645 64880 56764 65924 57435 Tested-by: Len Brown <len.br...@intel.com> thanks, Len Brown, Intel Open Source Technology Center -- 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/
