According to this ahash is faster:

Did anything change?

I am also wondering whether ahash is faster. ahash is developed with rust. We need a head to head comparsion. However, it is not available in SMHasher package.

Apparently there is a patch for the SMHasher here which adds support for ahash:

https://github.com/tkaitchuck/aHash/tree/master/smhasher

There are also ahash's own benchmarks here:

https://github.com/tkaitchuck/aHash/blob/master/compare/test...

They use the wyhash Rust crate, so if wyhash itself was updated doing a head to head comparison would boil down to updating the wyhash crate and rerunning ahash's benchmark suite.

Interestingly this patch never was submitted to me. Just saw it now. Will add it asap.

Very interesting is his claim to create wyhash collisions at will. Even with bad keys, not bad seeds!

It may be the fastest rust hash, but certainly not faster than other fast hashes. More like 2x slower.

xxh3, t1ha0, wyhash are all much faster on the 2 machines I tested it on, an old 7 years old Intel i5-2300, and a new Ryzen 3200U.
