Slow upload speed to QNAP NAS since Build 1809 and 1903 RRS feed

  • Frage

  • Untill W10 Build 1803 uploading files to a QNAP NAS (different NAS's and different firmware) was stable and on average 2,5 to 3mb per second.

    Build 1809 and 1903 have an average of 400kb p/sec. 

    This is normal NFS file uploading via Windows explorer.

    Can anybody tell whats happening?

    This is reproducible on the different Windows build

  • Hello Ravestein,

    Are the NFS versions used by these machines the same?

    Are these machines in the same network environment?

    Do slow upload machines need to go through some other routers/switches?

    "This is reproducible on the different Windows build"

    You mean the other 1809 and 1903 machines are all slow to upload, right?

    Best Regards,

    Leon

  • Leon,

    I have 3 machines beside each other and I upload a file (500mb) to a nas. All to the same location.

    1 Build 1803, 1 Build 1809 and 1 build 1903.

    Only Build 1803 is fast, the other 2 are slow.

    Something has changed in build 1809 and 1903 that makes uploading slow.

  • Hello Ravestein,

    I also think that some patches may affect the 1809 and 1903 machines.

    But I don't have NAS device and can't verify it with experiments.

    Besides, why don't you use the SMB protocol to let clients communicate with NAS devices?

    Best Regards,

    Leon

  • OK. Then I will continue to keep this post open, and maybe others can provide some ideas.

    Also, you can try to use SMB protocol to let clients communicate with NAS devices to see if the situation is different.

    Best Regards,

    Leon

  • Hello Ravestein,

    When you speak of "NFS" do you specifically mean the Network File System protocol originally developed by Sun Microsystems or is it used in generic way to cover any type of network file sharing?

    That question aside, open could make short network traces of a file transfer from both 1809 and 1903 systems and look for differences in TCP window size, scaling, etc.. Once we have identified at a network protocol level a possible cause for the speed difference, we will be in a better position to know which aspect of the Windows configuration to look at more closely.

  • I am experiencing the exact same issue, on thunderbolt 3, 1809 was working fine transferring around 1.2GB/sec now on 1903 its less than 400kb/sec or less, updated all drivers for thunderbolt but no go, go back to 1809 works fine.

  • For me, exactly the same.

    How can you go back to 1809?
