With 7 threads I'm getting about 2.30 KH/s! (I didn't run 8 threads cuz my boy is using one core for Minecraft, lol...)
results are really impressive! I can provide two values which were collected by using poor guys hardware:
Xeon E5 2603 V3 (original) - 0.62 KH/s
Xeon E5 2637 V3 ES QEYT (default overclocking in bios) - 1.08 KH/s
BTW I was able to catch 1000 SLD block by using Xeon E5 2603 v3
