XXH3 – a new speed-optimized hash algorithm
The end result of this investigation is , a cross-over inspired by many other great hash algorithms, which proves substantially faster than existing variants of xxHash, across basically all dimensions. Thing is, most modern hash algorithms take advantage of 64-bit instructions, which can ingest data twice faster, so it’s key to great speed. For this reason, I will distinguish both variants in the graph, as the speed difference on small inputs is quite noticeable.
