Lan speed

  • Hi, I have problem with lan speed. I have transfer about 25MB/s in 1Gb lan. According to specification my NAS (WD My Cloud) should has Gigabit Ethernet port. I found that 100Mb connection has a green light and 1Gb has amber light. I discovered that my computer has amber light but NAS has green one.
    I made also crossed cabel and connect computer and NAS without any switches, my speed was a lite bit more about 30MB/s.
    Can some help me, maybe I should change something in OMV 2.1.17.


    Thanks for help.

  • Hi, command: ethtool eth0 give results:

  • I put to SMB etra option: max protocol = SMB2
    nothing changed still uplod speed to NAS about 25MB/s, download speed about 38-40MB/s


    after that I found next solution and put:


    max protocol = SMB2
    max xmit = 65535
    socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=65535 SO_RCVBUF=65535
    read raw = yes
    write raw = yes
    max connections = 65535
    max open files = 65535


    also nothing changed still the same speed.



    I've inastalled Fox_exe version 1.16a and I've updadted to 2.1.17.

  • uplod speed to NAS about 25MB/s, download speed about 38-40MB/s


    Its normal for WD MyCloud (CPU: 2 cores, 650MHz).
    For better speed WD provide one trick - they use non-standart "Memory page size" with 64kb (4kb in normal kerel).
    Its unstable, but works.


    Without this patch Samba can get maximum ~50MB/s Download and ~30MB/s upload.
    Also connect shared folder as "Network drive".
