note: some algorithms feature _faster than RAM_ speed. In which case, they can only reach their full speed when input data is already in CPU cache (L3 or better). Otherwise, they max out on RAM speed limit.
note 1: Small data velocity is a rough evaluation of algorithm's efficiency on small data. For more detailed information, please refer to next paragraph.

### Small data
Performance on large data is only one part of the picture.

Aside from the C reference version,
xxHash is also available in many different programming languages,
thanks to many great contributors.

### Special Thanks
Takayuki Matsuoka, aka @t-mat, for creating `xxhsum -c` and general support during early xxh releases
Mathias Westerdahl, aka @JCash, for introducing the first version of `XXH64`
Devin Hussey, aka @easyaspi314, for excellent low-level optimizations on `XXH3` and `XXH128`
