SMhasher is a test suite for evaluating the quality and speed of non-cryptographic and cryptographic hash functions. It benchmarks throughput and runs statistical quality tests, publishing comparative results for dozens of hash implementations.

Use cases

• benchmark hash function speed in MiB/sec
• test a custom hash function for quality problems
• compare hash functions for hash table use
• check a hash function for collisions and distribution issues
• find the fastest 64-bit hash for my use case
• verify hash function seed independence

When to choose

• you need to validate or benchmark a hash function implementation
• you want authoritative comparative data on hash function quality and speed
• you are selecting a hash function for hash tables or checksums

When to avoid

• you need a hash function library to embed rather than a testing tool
• you need cryptographic security certification rather than statistical testing
• you need application-level hashing utilities
