A nice overview is listed here: https://github.com/tkaitchuck/aHash/blob/master/compare/readme.md comparing aHash to other algorithms. aHash passes the full suite of https://github.com/rurban/smhasher , FnvHash has some weak points. @andygrove any way to test it? I recently also used it for the polars project where it brought around 20-30% speed ups to group by and hash join vs SeaHasher (which already should be faster than FNV): https://github.com/ritchie46/polars/pull/128 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
