> xxh3 is a new hash algorithm by Yann Collet that claims excellent speed on
> both small/tiny and large keys. It has accelerated paths for x86 SSE2, AVX
> and ARM NEON. It also has excellent hash quality.

> Perhaps this can replace our current complex strategy involving a custom tiny
> string hashing implementation, a HW CRC32-based path where available for
> large strings, and a murmurhash2 fallback.
