I’ve just replaced MetroHash with CityHash and get 1000x (30ms instead of 30s) hashing speedup. It seems I somehow screwed MetroHash really bad. #cpp
I'd be interested to see the benchmark. Also, we _do not_ require aligned inputs, but they say we do, so maybe they are not really using Meow Hash?

Either way, I'd never heard of "mum hash", but now that I have, I'll add it to our benchmark and we can see how it actually performs under controlled conditions.

I went ahead and benchmarked it. It is slower than us on all input sizes. It is also slower than other relatively fast hashes at small sizes, such as t1ha and xxhash3, although it may be higher quality than those, I don't know... more on that later :)
