MurmurHash is a fast non-cryptographic hash function created by Austin Appleby. It's optimized for hash tables, providing excellent distribution and speed. MurmurHash3 is the latest version.

MurmurHash is used in Redis, Memcached, Cassandra, Elasticsearch, libstdc++ hash tables, nginx, and many databases and caching systems.

MurmurHash1 (deprecated), MurmurHash2 (32/64-bit), and MurmurHash3 (32-bit, 128-bit x86, 128-bit x64). MurmurHash3 is recommended for new projects.

No. MurmurHash is designed for speed and distribution, not security. It's vulnerable to hash-flooding attacks. Use SHA-256 or SipHash for security.

MurmurHash processes multiple bytes per iteration, uses simple multiply and rotate operations, and has excellent instruction-level parallelism on modern CPUs.

Any 32-bit value works. Use 0 for deterministic hashing, or random seeds to prevent hash collision attacks. Different seeds produce completely different hashes.

x86 produces 32-bit or 128-bit output optimized for 32-bit CPUs. x64 produces 128-bit output optimized for 64-bit CPUs with different mixing functions.
