I could not resist to throw all relevant trees on my own 4node machine and run a SPECjbb 4x JVM comparison. All results have been averaged over 10 runs. mainline: v3.7-rc8 autonuma: mm-autonuma-v28fastr4-mels-rebase balancenuma: mm-balancenuma-v10r3 numacore: Unified NUMA balancing tree, v3 The config is based on a F16 config with CONFIG_PREEMPT_NONE=y and the relevant NUMA options enabled for the 4 trees. THP off: manual placement result: 125239 Auto result Man/Auto Mainline/Auto Variance mainline : 93945 0.750 1.000 5.91% autonuma : 123651 0.987 1.316 5.15% balancenuma : 97327 0.777 1.036 5.19% numacore : 123009 0.982 1.309 5.73% THP on: manual placement result: 143170 Auto result Auto/Manual Auto/Mainline Variance mainline : 104462 0.730 1.000 8.47% autonuma : 137363 0.959 1.315 5.81% balancenuma : 112183 0.784 1.074 11.58% numacore : 142728 0.997 1.366 2.94% So autonuma and numacore are basically on the same page, with a slight advantage for numacore in the THP enabled case. balancenuma is closer to mainline than to autonuma/numacore.
