29 xxHash is an Extremely fast Hash algorithm, running at RAM speed limits.
30 It successfully completes the SMHasher test suite which evaluates
31 collision, dispersion and randomness qualities of hash functions. Code is
32 highly portable, and hashes are identical on all platforms (little / big
33 endian).
