According to Daniel Jordan's suggestion, I run 64 'dd' with on 32 containers on my 2s* 8 core * HT box with the modefied case: https://git.kernel.org/pub/scm/linux/kernel/git/wfg/vm-scalability.git/= tree/case-lru-file-readtwice With this change above lru_lock censitive testing improved 17% with multi= ple containers scenario. And no performance lose w/o mem_cgroup. Thanks Hugh Dickins and Konstantin Khlebnikov, they both brought the same= idea 7 years ago. Now I believe considering my testing result, and google inte= rnal using fact. This feature is clearly benefit multi-container users. So I'd like to introduce it here.
