New high-quality hash measures 71GB/s on M4

rapidhash - Very fast, high quality, platform-independent The fastest recommended hash function by SMHasher. The fastest passing hash in SMHasher3. rapidhash is wyhash' official successor, with improved speed, quality and compatibility. Fast Extremely fast for both short and large inputs. Surpasses 70GB/s on Apple's M4 cpus. The fastest hash function passing all tests in SMHasher. The fastest hash function passing all tests in SMHasher3. Universal Optimized for both AMD64 and AArch64 systems. Compatible with gcc, clang, icx and MSVC. It does not use machine-specific vectorized or cryptographic instruction sets. Prepared for both C and C++ compilation. Excellent Passes all tests in both SMHasher and SMHasher3. Collision-based study showed a collision probability lower than wyhash and close to ideal. Outstanding collision ratio when tested with datasets of 16B and 66B keys: Input Len Nb Hashes Expected Nb Collisions 8 15 Gi 7.0 3 12 15 Gi 7.0 4 16 15 Gi 7.0 8 24 15 Gi 7 ... Read full article.
