| Summary | 0000858: Check for update of hash calculations to xxHash | ||||
| Description | Yet another extremely fast non-cryptographic hash algorithm surfaced, that might be worth looking at: http://www.xxhash.com/ Compared to our current Murmurhash it promises another doubling in speed while maintaining quality. Also, it is BSD-licensed and promises the same hashes on 32/64 bit and LE and BE machines. Should be evaluated for 3.6.0. | ||||
