# XOR
|
||
|
|
|
||
|
|
XOR code engine in pure Go
|
||
|
|
|
||
|
|
more than 10GB/S per core
|
||
|
|
|
||
|
|
## 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
|
||
|
|
```
|
||
|
|
| data_shards | shard_size |speed (MB/S) |
