Quoting from https://eightomic.com/hash-32-a/ | EIGHTOMIC HASH 32 A: THE FASTEST 32-BIT, OAAT HASHING ALGORITHM VERSUS | CDB AND DJB2 While I doubt there's a performance improvement at all and if there is it won't be measurable in this context, reading the footer of that page makes me wonder whether the given algorithm is suitable for use in a GPL licensed project to begin with.
