Hash Algorithm Benchmarks
Tested on AMD Ryzen 9 5900X, 32GB DDR4-3000 (16-17-17-35) Tested on the Rust rapidhash port test suite
Pure Hashing Speed
Non-portable implementations are marked with an asterisk (*).
This measures the performance of the streaming API only.
This doesn't measure the performance of the oneshot implementation; i.e.
when the full length of data is known. Only the rust Hasher streaming API
is measured; this can be very inefficient for some implementations.
The oneshot implementation of XXH3 sits between rapidhash and wyhash for
reference, before starting to run away at 512 bytes and beyond due to hardware
acceleration.

Observations
Key observations:
- gxhash dominates long data but isn't portable
- For short strings, fxhash and rustc-hash are very competitive speed wise
- rapidhash variants show very consistent performance
- For u64/object hashing, rustc-hash and fxhash are the clear winners
- Rust implementation of
xxhashhas high startup overhead. But wins out on long data due to SSE2/AVX2.

Observations
- For text:
- fxhash and rapidhash are clearly the leaders
- rapidhash variants show very consistent performance
-
default hasher significantly trails all others
-
For non-text:
- rapidhash variants show excellent all-round performance
- gxhash excels at struct handling but isn't portable
- fxhash is best for integers but struggles with structs
- default hasher is consistently slowest
