I have strange issue with x5677 CPU. One has Vmware installed, and a virtual machine with 6 vCPU has lscpu output,

And a single 6-thread STH container give me 300H/s.
Another one has Ubuntu installed on bare metal, lscpu output,

I use CPU 1,2,5,7,9,10 for 1st container, and 0,3,4,6,8,11 for 2nd container, but each only gives me 230H/s. The NUMA node CPU ID just look weird on bare metal.
