You can pick it up via: > > http://people.redhat.com/mingo/sched-devel.git/README Yanmin, how do you use volanomark; I got it from: http://www.volano.com/benchmarks.html and am using java-1.6.0-openjdk.x86_64 I installed it /dev/shm/vmark to avoid disk io ruining anying But I'm getting very fluctuating results, from ~43000 msgs/s to 52000 msgs/s. This makes it very hard to 'trust' this benchmark, let alone determine a regression. -- 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/
