There are several examples of really amazing and extremely fast move generators:

jordanbray/chess looks to be probably the most performance-optimized Rust move generator.
World's fastest Bitboard Chess Movegenerator seems very complicated but incredibly fast.

What needs to be done here is bringing the performance closer to the ones mentioned. That means

Adding baseline benchmarks
Significantly improving the performance of existing code

Currently, the CPW perft(7) challenge positions take too much time to process. It should be possible to get extra 2x-3x speedup.

E.g. on https://www.talkchess.com/forum/viewtopic.php?t=59781 position rnb1kbnr/pp1pp1pp/1qp2p2/8/Q1P5/N7/PP1PPPPP/1RB1KBNR b Kkq - 2 4 it takes about 4 minutes which is way too long.
