Hi doktor83,

I am doing a lot of tests on CPU mining with RandomX algo.
I am using version 0.1.6 on a Fujitsu Primergy RX2560 M1 server.
I have two Intel XEON E5-2630 V3 @ 2.40GHZ 16 cores, 32 threads available

I would like to share my results with you and discuss about hyper-threading option.

1st test (WITH hyper-threading option enabled in BIOS, default option) :

- 16 cores, 32 threads available
SRB uses only 16 threads with auto config with a speed of 4400 Hr / s

1 in 2 thread is not used when analyzing processors activity.
I tried to play with the CPU Affinity and CPU Thread options but could not get better than 4400. If I force 32 threads (or 24, or 30) with the CPU threads option I get a ridiculous speed .

2nd test (WITHOUT hyper-threading option activated in the BIOS) :

- 16 cores, 16 threads available.
SRB uses 15 threads in auto setup. The speed increases a bit, 4900Hr / s

So I would like to know if you knew about it and if you intended to add in your code the hyper threading. If you do not plan to work on it maybe you could warn people not to use the hyper threading option to have a better Hr / S.
I think if hyper-threading option can be manage in SRB we can get maybe 1.6x more speed, what do you think ?

Thank you for your feedback on the subject Smiley
