## 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) |
