Hi,
Thanks for reporting this benchmark results, but you mentioned the "V9 patch
series" while responding
Some regression and improvements is found by LKP-tools(linux kernel
performance) on V9 patch series
tested on Intel 4s Skylake platform.
The regression result is sorted by the metric will-it-scale.per_thread_ops.
Branch: Laurent-Dufour/Speculative-page-faults/20180316-151833 (V9 patch series)
