    Ok, I have a problem With my home network being so slow that coping 1gb take over and 1 hour. But on the same system Windows 8 can copy at over 20mb/s. I have also ran XP pro in virtual machine and saw 20mb/s +, Host was Windows 7. I really do not understand this, I have read so many forums and none of them have fixed my issue, Im not upgrading to Windows 8 as its just not going to work for me.

    For example, I can transfer a 107mb video file from Windows 7 x64 to Windows 8 x64 and the transfer rate is lucky to pass 500kb/s. But from Windows 8 to windows 7 I can get 2.4mb/s, its better, but not really what I want.

    Note: I can transfer the same 107mb file Within XP running on VM ware at 20mb/s while I see the 40% utilization on the network card, but within the host OS (Win 7), like I said, Im lucky to get 500kb/s. 

    Now don't say my HDD is slow or its the bottleneck, I mean yes it is, but 500kb/s? Come on now, I can transfer files back and forth all day at 100mb/s, 60mb/s to USB devices.

    Its sad when you pay this much for an OS and not be able to use it to share file within my own network. Its a problem, it has been a problem since 2009 from some other posts. If Windows 8 was usable for my programs, I'd switch to it, Metro interface I learned to work around it, but some of my software will not work in that OS, and I do not feel like re installing 500GB+ of software and finding out which works and don't.

    System:

    OS: Windows 7 x64 Ultimate

    CPU: AMD Phenom II x6 1100T 4.1ghz

    RAM: 16GB corsair Vengeance 1600mhz

    MOBO: ASRock 990FX Fatality Professinal (slow speeds on both Ethernet ports)

    VIDEO: 2x HD5850's crossfire

    PSU: Corsair GS700

    Without any research or looking into this, I would think the issue was related to something 'looking' at the files coming across the network or with the way your net adapters handle large files.

    As a TEST, temporarily turn off the firewall between the two systems and try the copy. Then try the same test with AV off. Try both off. Is the result the same?

    Another option is to enable Jumbo Packet (frames) in your network adapter settings. This is primarily used to increase speed when transferring large files within your network. The packet size options are dependent on your adapter/driver. It has been some time since I've messed with this, but it did seem to improve performance when I was transferring some 3-5GB movies from one PC to another.

    Here is an article on it...there are several others out there as well.

    Hi,

    In addition to the problems provided by Zrider, I also would like to share the following with you:

    1. Keep the Network Adapter up-to-date.

    2. Try this hotfix in the following KB:

    Slow data transfer speed in Windows 7 or in Windows Server 2008 R2

    http://support.microsoft.com/kb/2675785

    3. Run the following command:

    Netsh int tcp set global autotuninglevel=disabled

    netsh int ip set global taskoffload=disabled

    netsh int tcp set global chimney=disabled

    Regards,

    Yolanda
