XOR

XOR code engine in pure Go

more than 10GB/S per core

Introduction:

Use SIMD (SSE2 or AVX2) for speeding up
...

Installation

To get the package use the standard:

go get github.com/templexxx/xor

Documentation

See the associated GoDoc

Performance

Performance depends mainly on:

SIMD extension
unit size of worker
hardware ( CPU RAM etc)

Example of performance on my MacBook 2014-mid(i5-4278U 2.6GHz 2 physical cores). The 16MB per shards.

speed = ( shards * size ) / cost
