I repeated some of the tests across NFS, where I'd expect to see bigger differences. Best of 20 values reported in "min ...". webkit Stock min 9.61 avg 11.61 +/- 1.35 max 14.26 Duy min 6.91 avg 7.67 +/- 0.46 max 8.71 linux Stock min 2.27 avg 3.16 +/- 0.56 max 4.49 Duy min 2.04 avg 3.12 +/- 0.69 max 4.87 libreoffice-core Stock min 4.56 avg 5.79 +/- 0.79 max 7.08 Duy min 3.96 avg 5.25 +/- 0.95 max 6.95 Similar 30%-ish speedup on webkit. And an absolute gain of 2.7 seconds is quite nice. -- Pete -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
