Fishtest with Stockfish 11 had 1.6Mnps as reference nps and 0.7Mnps as threshold for the slow worker. Set the new reference nps to 560knps according to the 65% slowdown of SF16 with SFNNv8:L1-2560 wrt SF11 on ARCH=x86-64-bmi2 Set the new threshold for slow worker to 203knps according to the 71% slowdown of SF16 with SFNNv8:L1-2560i wrt SF11 on ARCH=x86-64-sse41-popcnt compiler clang++ 16.0.6 - arch=bmi2 (Intel Xeon CPU E5-2680 v3) ``` sf_base = 1579950 +/- 8197 (95%) sf_test = 555524 +/- 4331 (95%) diff = -1024426 +/- 6115 (95%) speedup = -64.839% +/- 0.387% (95%) ``` - arch=sse41-popcnt (Intel core i7 3770k) ``` sf_base = 1790486 +/- 19610 (95%) sf_test = 532610 +/- 6143 (95%) diff = -1257876 +/- 13960 (95%) speedup = -70.253% +/- 0.780% (95%) ``` Raise worker version to 218, also server side.

This is the computation using SF16 as reference, as asked on Discord. I can update the PR if it's preferable. Fishtest with Stockfish 16 (#1735) had 1.184Mnps as reference core nps and 0.462Mnps as threshold for the slow worker.

Set the new reference nps to 560knps according to the 65% slowdown of SF16 with SFNNv8:L1-2560 wrt SF11 on the ARCH=x86-64-bmi2
Set the new threshold for slow worker to 203knps according to the 71% slowdown of SF16 with SFNNv8:L1-2560i wrt SF11 on the ARCH=x86-64-sse41-popcnt
