10000 @ 60+0.6 th 7 Test per-thread counterMoveHistory, people reported that in case of big NUMA machines, like TCEC superfinal one, this could lead to big nps improvement. We need at least 7 threads and at least 60 secs/game to have a sensible measurement of the possible ELO loss. Set with high priority because TCEC superfinal is near and we need many tests to validate this solution.
