t1ha
A fast portable non-cryptographic 64-bit hash function optimized for modern 64-bit CPUs, often outperforming xxHash and StadtX.
What is t1ha?
t1ha (Fast Positive Hash) is a portable non-cryptographic 64-bit hash function designed for high performance on modern 64-bit CPUs, particularly x86_64 and Elbrus architectures. It provides fast hashing for use cases like checksums, hash tables, and data fingerprinting, often outperforming other portable hash functions like xxHash and StadtX. The library includes multiple variants optimized for different trade-offs between speed, stability, and quality.
Developers and engineers working on performance-sensitive applications requiring fast hashing for data integrity, hash tables, or fingerprinting, especially those targeting 64-bit systems.
t1ha offers exceptional speed—often 15% faster than comparable portable hash functions—while maintaining good quality and portability across platforms, with hardware acceleration support and a permissive zlib license.
