Низкая скорость передачи через Samba с использованием программного RAID

В системе GNU вы можете сделать что-то вроде:

find. -name '*.md' -print0 |
  gawk -v RS='\0' -F/ -v OFS=/ '
    {filename = $NF; NF--
     if ($(NF)".md" == filename) include[$0]
     else exclude[$0]
    }
    END {for (i in include) if (!(i in exclude)) print i}'

aio read size (S)

If this integer parameter is set to a non-zero value, Samba will read from files
asynchronously when the request size is bigger than this value.
Note that it happens only for non-chained and non-chaining reads and when
not using write cache.

The only reasonable values for this parameter are 0 (no async I/O) and 1 (always do async I/O).

same is said for aio write side

Я рекомендую удалить эти два из вашего smb.conf. Я никогда не использовал эти два в своем smb.conf.

Я получаю скорость чтения/записи 112 МБ/с в течение всего дня по проводной сети 1 Гбит/с на/с ПК с Win10, для справки, вот мой глобальный раздел smb.conf 

[global]
    workgroup = SAMBA
    security = user

    passdb backend = tdbsam

    printing = bsd
    printcap name = /dev/null
    load printers = no
    disable spoolss = yes
  # cups options = raw

    smb encrypt = required
    client min protocol = SMB3
    client max protocol = SMB3

в RHEL 7 настроенные профили для справки
