For those that just want to see the graph ( sorry - it's fuzzy - go to the website above to see clearer image - its 37 to 39M nps, as an asie, the 2970 Threadripper comes in at 50M nps, and the 2990 Threadripper is about 60M. But the 2970 is just 24 cores.

After I installed the latest Mint on my laptop. I noticed a huge boost in search speed ( +1 mnps ). Movegenerator ( +10 mnps ).

I remember Sapeli searching 3.8 - 4.2 mnps on this laptop. Now Sapeli is searching almost 6 mnps. I used gcc7.2 earlier So the speed up is coming from OS.

Notice a big boost after I closed Firefox. It/other programs seems to hog lots of resources.
