It seems not applied to acme/perf/core cleanly.

It seems the patch mail is truncated. :(
I attach the patch file in the mail. Sorry for inconvenience.
I've checked it fixed the perf test on my laptop (skylake).

Can I get ACK for this patch?
It's mainly for fixing the perf-test issue and MEM_Parallel_Reads issue.
Thanks
