Flamegraphing showed bigint to be problematic. It turns out its deprecated and the community is using uint. It provides a ~10x speedup I got 1-2k hashes on a raspberry pi 4 and ~8k on a low end Dell XPS laptop (game not running ~5k with game taking threads). But Digital ocean 24cpu pulled ~28k hashes when benchmarked it.
