Improve speed, only 50MB/s

  • Hi,


    I have installed OMV on a microserver gen8, the OS is in a SSD and i a have 2x6TB in mirror and 1TB.


    Write on both HDD don't exceed 60MB from a WINDOWS 7 PC, while the drive tests from the microserver have achieved min 100MB.


    I also used iperf to test my wired connection, i have almost 1Gb both ways.


    I tried the max protocol option but didn't improve the speed.


    Would you have any advice?
    Could it be due do the CPU?


    Thank you

    Did you read the Solution to Common Problems thread at the top of every forum section? - Solutions to common problems


    Could it be due do the CPU?

    No, it will saturate gigabit easily.

  • Which file system do you use ? Might be a block format thing with yout 6To disk as if you have 50MB/s between disks inside the server, that's no a network problem...

  • Maybe the blocks of the disks are not align with the one of the FS...
    Check your disks block size of your hardware, and compare it to the ext4 block size

    You can also try to make some runs with basics tests speed with dd and hdparm :
