Use huge pages for worker data As the worker data is quite large (28MB after #6350) we can make use of huge pages as a speedup. prior to #6350 STC passed elo gaining bounds: LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 166272 W: 43479 L: 42993 D: 79800 Ptnml(0-2): 540, 17598, 46365, 18102, 531 https://tests.stockfishchess.org/tests/view/68e9f3c0d323fd15c04e3ba4 Tested the speedup on a large machine with speedtest: ==== master ==== Average (over 20): 288644510 ==== largePageWorker ==== Average (over 20): 292082422 Test after #6350: ==== rustam-cpp-testPR ==== Average (over 20): 291035351 ==== rustam-cpp-testPR-pages ==== Average (over 20): 291937367 https://github.com/official-stockfish/Stockfish/pull/6359 No functional change
