@jedisct1 on it! for now we're using the canonical C keccak implementation to get within ~4% of the rust performance.
a lot of our optimization efforts right now are toward u256 ops, since that's highest impact for our users, but we will get to the general zig keccak improvements soon!
@FUCORY the issue link is our bad! this PR is for your suggestion re: zbench and keccak observations, we opened a separate one that solves your issue :)
We contributed our changes to the zig standard library as well, and plan get to faster constant time optimizations for some more algorithms directly needed by searchers (keccak is next)
