hash/maphash is slow
1 project | /r/golang | 12 Feb 2023

It depends on the architecture like amd64 it’s naturally fast but for amd and the rest is kinda of slow because Go uses AES hashing algorithm upcoming they’re planning to change the hashing alg either xxhash or swisstable I recommend you use 3rd party maphash like https://github.com/alphadose/haxmap or any

I shall add a 32 bit variant of haxmap too in the near future using this 32 bit variant of xxHash https://github.com/pierrec/xxHash/tree/master/xxHash32
