How to get most of lolz parallelism

[elit]

KAktoR do you happen to have Ryzen 2600 variant(6C12T)? If so then the fact that you can still actually see any benefits with max threads - and even more so when half is just HT, is good information to know.
Btw I dont see why input data should matter as long as its same for all tests. We should only care about different threads on same processor(measuring effectiveness), its not about my CPU vs yours just ot be clear(but yes, I too believe different input data do affect speed of lolz - from my observation).

If you have 2600 or similar those one have a huge L3 cache, although I would also try 2-3T. 2600 also have different design, it act as a NUMA but require external AMD application to switch the way cores work. You cound get a very different results with tweaking -mt and CPU mode.
