Vista Network Performance... again.

    Vista Network Performance... again.

    Good Day, folks.

    I am curious if anyone would have any suggestions regarding the poor
    network performance under Windows Vista Business. Before I get into
    the crux of the issue, I'll briefly describe my setup.

    Machine 1 - Windows Vista Business.
    Machine 2 - Windows XP Professional.
    Machine 3 - FreeBSD 6.2-Stable Workstation.
    Machine 4 - FreeBSD 6.2-Stable Server.

    The server houses a 2.5TB RAID 5 array with a 3Ware hardware-based RAID
    controller. All of the machines have at least 2GB RAM, C2D processors and
    gigabit Ethernet. The router/switch is gigabit capable, although it does
    not support jumbo Ethernet frames.

    The basic issue is that transfers from, or to, the Vista machine are
    typically 75% less than any of the other machines:

    Server <-> XP or the workstation yields approx. 35MB/sec to 55MB/sec.
    Server <-> Vista yields approx. 4MB/sec to 12MB/sec.

    This is not a machine specific issue as I've installed FreeBSD for testing
    purposes on the machine that Vista is currently installed on and network
    performance was as expected with an average of 50MB/sec on the same hardware.

    I've tried a number of suggestions as per numerous websites, as well as
    these newsgroups. Some of these suggestions include:

    - Disabling Remote Differential Compression.
    - Disabling TCP Autotuning.
    - Installing Hotfix KB931770.
    - Disabling Indexing.
    - Updating the NIC drivers to the latest available.

    Although the above did increase throughput by about 1-2MB/sec, this
    is still rather unacceptable. I tend to find it rather hard to believe
    that an issue such as this is still present months after the general
    release of Vista, and one that is rather widespread based on various
    newsgroups and web-based forums.

    I am really hoping that someone could provide suggestions that would
    remedy this issue. I routinely push multi-gigabyte files to and from
    the server from this machine, and this performance issue is getting
    painful to deal with.

    Any help and/or suggestions would be most appreciated.

    Seeing as you have tested it on both machines try disabling the firewall!

    The performance monitors in Vista will automatically ajust every type of data transfer and if theres not enough for a program to work with it will slow the extra non system stuff right down...there might be some help here (link) How to Fix Windows Vista Slow Network Transfer » ADS-Links.com Internet Marketing - Ian Lee

    There is a few other windows options to try if its really essential but a more simple way is just to use a ftp server.

    Thaks for the link, but unfortunately, none of that either applies or has
    already been attempted. The fact of the matter is that Vista is degrading
    my network throughput by, in most cases, over 75%. This is absolutely
    unacceptable.

    I routinely push ~25-30GB of data to and from the server daily. I do a lot
    of video encoding with this machine, and the abysmal transfer rates have
    a large impact on my application.

    This isn't really much of an option, as the application that I utilize
    doesn't support FTP transfers. On the server side, Samba is being utilized
    to provide share access to the RAID volume for the Windows clients. A
    drive letter is simply mapped to this share on the server and my application
    goes about its' business with that mapping. Trying to hack in the use of
    FTP into the workflow adds unnecessary manual intervention and won't solve
    the network issues.

    One thing that does strike me as odd, and perhaps is a start into trying
    to get this resolved; I attempted to copy a few files from the Vista machine
    to the server from a command prompt using `xcopy`. Transfer rates peaked
    at about 18MB/sec for large file copies to the server. When attempting to do
    the same from Explorer, transfers again dropped to about 6MB/sec. There is
    some really odd stuff going on with Vista. When I tried to do the same thing
    from a command prompt using `robocopy`, transfer rates also dropped to about
    7-8MB/sec.

    Thanks for the link and the suggestions. It was appreciated.

    All of the machines on the network are firewalled at the router. None
    are firewalled locally. None of the machines, except the Vista machine,
    are experiencing throughput issues. It's not a firewall issue.

    Thanks for the suggestion, however. It was appreciated.

    Re: Vista Network Performance... again.

    Firstly, sorry for waking an old thread.

    I'm having the same issue though.

    It seems I'm stuck on 100mbit even though both NIC's (on the server and on the client) link at 1Gbps. I've disabled the QoS scheduler and that helped a bit, I'm now getting 12.5MB/s at peak, where I got 11MB/s tops before.

    Anyone solved this issue?

    Re: Vista Network Performance... again.

    did you enable/disable IPV6?

    I've tried that yes, no result.
    Also tried using total commander for copying, no change.
    I even tried installing ipv6 on the server (windows 2003), but no luck.
