This implementation provides a fast pure-Go implementation and an even faster
assembly implementation for amd64.
The package is written with optimized pure Go and also contains even faster
assembly implementations for amd64 and arm64. If desired, the `purego` build tag
opts into using the Go code even on those architectures.

This implementation provides a fast pure-Go implementation and an even faster
assembly implementation for amd64.
The package is written with optimized pure Go and also contains even faster
assembly implementations for amd64 and arm64. If desired, the `purego` build tag
opts into using the Go code even on those architectures.
[xxHash]: http://cyan4973.github.io/xxHash/
## Compatibility
This package is in a module and the latest code is in version 2 of the module.
You need a version of Go with at least "minimal module compatibility" to use
github.com/cespare/xxhash/v2:
* 1.9.7+ for Go 1.9
* 1.10.3+ for Go 1.10
* Go 1.11 or later
I recommend using the latest release of Go.
## Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly
implementations of Sum64.
