Add document for native raw erasure coder in XOR codes.
This message was automatically generated.
Looks mostly good to me.
For default RS codec, there is also a native implementation which leverages Intel ISA-L library to improve the encoding and decoding calculation.
You may want to be more specific by saying "to improve the performance of codec."
Thanks so much Wei-Chiu for reviewing the patch! I have uploaded a new patch address the issue.
