I have been running the latest XMR-STAK-CPU-DEV on my dual E5-2667 V3 ES pc and it LOVES IT!!
It runs about the same H/s using only 16 cores, desktop is SUPER responsive its almost like its not even mining at all.

So I tried it on one of the open compute nodes, totally different story.
Ran it for the first time using the recommended settings it tells you to copy and paste to the config.txt file.
It ran at 204 H/s
After much fiddling with the "low_power_mode" : true, "no_prefetch" : true, in the config.txt the best was 304 H/s on the dev version vs 868 H/s on the older version of xmr-stak-cpu.
So I copied the "low_power_mode" : false, "no_prefetch" : false, from the older xmr config.txt and it gets about 835 H/s.
Then I changed it from "no_prefetch" : false to "no_prefetch" : true and it gets about 850 H/s.
Then I tried that on the older xmr-stak-cpu-master version and it went from 868 H/s to about 850 H/s
So on the open compute nodes I will stick to the older version for now.
