File Sharing Extremely Slow - Only One Way

    Question

  • When using the Server 2012 desktop and copying files from the server to a Windows 8 PC's shared folder it transfers at almost 100MiB/s. When using the Windows 8 desktop and copying files from a Server 2012 shared folder to the local PC it transfers at < 1MiB/s.

    In both cases the server's and client's CPUs are both at 1-2% load.

  • file transfer speed is totally depends on the Hardware configuration you use at your place. Obvious server have good configuration than the client. Is not it?

    What is the RAM size of Windows 2012 server and Windows 8 Machine.?

    >>>>When using the Server 2012 desktop and copying files from the server to a Windows 8 PC's shared folder it transfers at almost 100MiB/s
    In this case Windows 2012 server HW is utilizing for file transfer/copy.

    >>>>When using the Windows 8 desktop and copying files from a Server 2012 shared folder to the local PC it transfers at < 1MiB/s.
    In this case Windows 8 machine HW is utilizing for file transfer/copy.

    What you just said is utterly wrong on so many levels...

    For anyone else reading this: In both cases files are being copied from Server 2012 to Windows 8 only. The speed difference depends on where the copy is initiated from for the exact same set of files.

    Run a iperf and NTtcp tests in both directions to figure out is it network (TCP) or SMB issue. Check cabling. Try to use direct connections (no switches). Play with NIC drivers (did you get new ones with the recent Windows update?) and so on.

    I had already run NTtcp and I get maximum bandwidth in both directions while running the sink on either system. The server is on ESXi 5.1 and uses the VMXNET3 NIC. As for the Windows 8 desktop I've tried older drivers from Marvell's website as well as the new Windows 8 drivers from Windows Update.
