I have a similar brute force with a build script implementation at https://github.com/zookini/aoc-2021/blob/master/src/bin/24c.rs . It uses dashmap with fxhasher and runs in 3.4 seconds on a Ryzen 5 5600X Six Core. It takes 15 seconds to run single threaded whereas std::collections::hashmap (also with fxhasher) takes 10 seconds
