Hi @qiqian , This is a great change but unfortunately it will break the library - kernel API which means releasing a major version. |

Hi, it's ok for me, I have made a local workaround to speedup memcpy, just wish it to be merged in the master branch, so I don't have to keep maintaining a custom branch :) |

memcpy can take advantage of erms or avx instructions on moden cpus
these instructions run much faster (up to 20% in my test case) on 64-byte aligned address
