Benchmark against Pleco? about chess HOT 4 CLOSED

I've performed a quick benchmark of pleco with chess_perft binary I wrote. Pleco does seem quite a bit slower than either shakmaty or this library (about a factor of 2.5 - depends on the position).

I'll do a more thorough analysis and update the chess_perft crate, with some graphs and whatnot.

Additionally, take a look at the chess_uci crate I wrote if you get a chance: https://github.com/jordanbray/chess_uci. It's not published on crates.io yet, but I hope to get it into a stable state soonish. My goal there is to deal with the uci protocol details and allow you to focus on the engine itself. Most of the pieces are there and it may make your life easier, if for nothing else than all the string parsing.

One other thing, make sure to enable opt-level = 3 in your Cargo.toml when using this crate because rust does a really bad job of generating code without optimizations. A small performance boost can also be achieved with RUSTFLAGS="-C target-cpu=native" which allows the use of some bitwise instructions.

Closing this in favor of jordanbray/chess_perft#1. This is where I keep the benchmarking code.

Thanks for the quick and detailed response! I really appreciate it. I'll be using chess for my engine. :) Also thanks for pointing me to your uci library! I'll definitely take a look at it, too.
