# XOR

XOR code engine in pure Go

more than 10GB/S per core

see: https://github.com/templexxx/xorsimd

## Introduction:

1. Use SIMD (SSE2 or AVX2) for speeding up
2. ...

## Installation
To get the package use the standard:
```bash
go get github.com/templexxx/xor
```

## Documentation

See the associated [GoDoc](http://godoc.org/github.com/templexxx/xor)


## Performance

Performance depends mainly on:

1. SIMD extension
2. unit size of worker
3. 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
```
