Hello @doktor83,
Some news with SRBMiner-MULTI 0.1.7 :
I use 2x Intel XEON E5-2630 V3 @ 2.40GHZ
16 cores, 32 threads available with Hyper-Threading
WITH Hyper-Threading option enabled :

- Only 50-55% processor activity
- Only 16 Threads used out of 32
- Around 4400Hr/s
- Can't get more with cpu-affinity and cpu-threads
WITHOUT Hyper-Threading option enabled :
https://zupimages.net/up/19/47/z2xe.png
- 100% processor activity
- 16 Threads used out of 16
- Around 4400Hr/s (less than previous version of SRBMiner MULTI 0.1.6 : 4900Hr/s)
-> Previous version used only 15 threads out of 16 in auto-config compare to 0.1.7
I use auto-config each time for doing tests

It is hard, or maybe not even possible at all to make the auto config work good on every system with different cpu combinations.
Ver 0.1.7 does the threads & affinity calculation in auto mode based on available L3 cache sizes, where 0.1.6 was not . The logic used there was really poor
So you can set --cpu-threads 15 by hand, without affinity set at all with the HT off, and should get the 4900h/s again.
