    Slow network performance

    Hi,

    I have a gigabit network with a netgear gs605 switch.

    When copying files from my windows 2003 machine onto vista it does it at
    only 5meg per sec. But if I reboot my machine in xp (its dual boot)
    and do the same i get my usual 50meg per sec.

    I've tried searching the net for the past 7 days but I have not found
    any solution to this. Can someone please offer some advice?

    I have updated the drivers for my network card to the latest Marvell
    Yukon drivers for vista.

    thanks.

    You're good. I'm getting only 2MB/s on gigabit.

    RE: Slow network performance

    I got exactly the same problem. I just installed Vista Ultimate 32 Bit this
    weekend and Network Transfers (GBit Ethernet) from the server to the client
    are extremely slow.

    With XP I got around 15 MBy/s, now I'm stuck at 5 MBy/s.

    I got a Marvel 8053 Networkchip on the Vista Machine, the Server Runs
    Windooze 2003 Server.

    Pls help

    I have the exact same problem - I am also running Ultimate, I get between 5
    and 8/sec - extremely frustrated

    Re: Slow network performance

    This doesn't help, I already tried it and just tried again - ran it from an
    elevated command prompt as admin - I still only get to 8MB/sec. I wonder
    when someone from MS will weigh in, I know at least 3 people with this issue.
    Is anyone reading this not having the problem? I'm running Ultimate, w Raid
    drive, Linsys router, 4MB RAM, connecting to Buffalo NAS and Server 2000 file
    stores

    I too am seeing extremely slow (4-7 mb/s) transfers under Vista (x86
    ultimate edition).

    Vista PC's hardware:

    - Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller (as
    reported by Vista - it's the onboard ethernet on an ASUS K8V)
    - Athlon 64 3400
    - 2gb RAM

    The switch is a Netgear GS608.

    Server-side is a dual xenon running CentOS 4.4 and Samba. When I boot
    the Vista box into XP I regularly get 300-400 mb/s transfers to the
    server.

    The degraded performance is not limited to SMB; I've tested FTP and
    netperf with similar results.

    Last night I installed the latest Marvell Yukon drivers available from
    the Marvell site. I think I got a slight improvement; nothing
    significant.

    I did notice (using Windows Task Manager) that my CPU is maxed out
    during transfers. I suspect there's a driver setting somewhere that
    is causing major CPU overhead. I don't see anything near this level
    of CPU use when achieving much higher transfer rates in XP.

    (Correction to above: I was seeing 30-40mb/s transfers under XP)

    I found two culprits. I uninstalled VMware Server 1.01 (and it's
    bridged and nat-ed interfaces) and my performance snuck up to 11mb/s
    (still pegging the CPU to 100%). I then installed a Realtek 8169S-
    based card in a free slot. After disabling my onboard Marvell Yukon
    I'm seeing ~20mb/s with CPU at 50-60% on the new card.

    So, if you're running VMware Server (and I suspect Player would have
    the same problem) I recommend uninstalling it until they get the
    performance thing straightened out. I also recommend the RTL 8169
    over the Marvell Yukon; again until they get the performance
    straightened out.

    Hope this helps.

    I'm having an issue using the Marvell Yukon 88E8001/8003/8010 on Vista
    Ultimate, any Gigabit switch and the Xbox 360 as a media center
    extender.

    Whenever the Yukon is in Gigabit mode playback of HD video on my 360
    tears & breaks up, de-sync's audio & video or just drops out
    completely, when I force the Yukon back to 100Mb by using a 100Mb
    switch or actually forcing the speed and duplex in the ethernet
    advanced settings playback is smooth with no issues.

    Can anyone else confirm this?

    Re: Slow network performance

    I tried that change and did not see any improvement. I did a big improvement
    with this:

    netsh interface tcp set global congestionprovider=ctcp

    while this made a big improvement, I think think it is as fast as it should
    be.

    There is another issue where Vista takes up to 30 seconds to resend a packet
    if lossed during transfer. See
    http://forums.whirlpool.net.au/forum...fm/720119.html for more
    infomation.
