I've just run specjbb2005 three times on my system both with and without cgroup_disable=memory on the command line and it is consistently 1% faster without memcg. If I add XX:+UseLargePages to the command line to use hugepages it's even larger. So why must I incur this performance degradation if I simply want to control who may mmap hugepages out of the global pool? The functionality to control this is pretty important if I want to ensure applications aren't able to infringe on the preallocated hugepages of a higher priority application for business goals. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
