## Introduction:

>- XOR code engine in pure Go.

>

>- [High Performance](https://github.com/templexxx/xorsimd#performance): 

More than 270GB/s per physics core. 

## Performance

Performance depends mainly on:

>- CPU instruction extension.

>

>- Number of source row vectors.

**Platform:** 

*AWS c5d.xlarge (Intel(R) Xeon(R) Platinum 8124M CPU @ 3.00GHz)*

**All test run on a single Core.**

`I/O = (src_num + 1) * vector_size / cost`

| Src Num  | Vector size | AVX512 I/O (MB/S) |  AVX2 I/O (MB/S) |SSE2 I/O (MB/S) |
