    Hi~
    I used `dd` command at ubuntu 16, and it was very slow when bs(block size) is small, only xKB/s in average.
    Here is my system information:Linux version 4.15.0-140-generic (buildd@lcy01-amd64-026) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.12)) #144~16.04.1-Ubuntu SMP Fri Mar 19 21:24:12 UTC 2021
