I used Jrockit and openjdk with Hugepage plus pin JVM to cpu socket. In previous sched numa version, I had found 20% dropping with Jrockit with our configuration. but for this version. No clear regression found. also has no benefit found. Seems we need to expend the testing configurations. :) -- Thanks Alex -- 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/
