Slow SMB speed - capped somehow to 1,8MB

    • Slow SMB speed - capped somehow to 1,8MB

      Hi there.

      I've installed OMV 2.x on the new server and somehow I'm unable to reach more then 1,8MB upload rate - this is the maximum I've reached after setting the extra options from thread:
      Extreme slow samba speeds

      Without this options I reach 1 - max 1,2MB upload rate. My internet connectivity is 50/50, confirmed also by the speedtest.

      This is test server, so I've provided it with only 4GB of ram and 2 vcpu, but during upload, load didn't jump even through I uploaded 600+ small files.

      Server info:

      There is only one nic on the server and it's on gigabyte link:

      Any thoughs what could be wrong/improved?

    • Yes, Parallels is hypersvisor.

    • Do you not have permissions to look up this info in Parallels? Just curious...

      I'm not sure what the problem is if you have an Intel network adapter. I would try install the backports 3.16 kernel (there is a button to install it in omv-extras).
      omv 4.0.14 arrakis | 64 bit | 4.13 backports kernel | omvextrasorg 4.1.1 plugins source code and issue tracker -

      Please don't PM for support... Too many PMs!
    • We've done some additional tests and we're somehow able to achieve 3-4MB without any problems. Weird, as nothing was changed.

      I though it could be maybe because I've updated OMV to 2.2.9., however I had one machine 2.2.6. and speed was also there. Most likely some internet issues internally. I will keep you updated if something changes.
    • Issue is still present - those 3-4MB was just temporary. Upload speed has been tested via 4 different locations and I've reached max 1,2 up to 1,8MB upload speed.

      I've even configured one ubuntu GUI machine in new datacenter which has link 150/150Mbits and I get upload speed via SCP 15-17MB, however smb traffic is capped as mentioned.

      Is there anything on the omv side I could do for this?
