Vista Gigabit Networking

[HEADRAT]

Hi,

I've got a Vista Ultimate box and 2 x MCE2005 linked up via a Gigabit network, now the transfer rates between the 2 x MCE2005 boxes are fine and if I push a file from the MCE2005 boxes to the Vista box again the transfer rate is what I expect (approx 20/30%)

Now if I try and push a file from Vista to either of the MCE2005 boxes then I get a throughput of about 6%!!

Anybody seen similar behaviour?

I've tried loads of different things but my Gigabit network just crawls.

1. Latest drivers for NIC's
2. Turning Remote Differential Compression off (no difference)
3. Settiing "netsh int tcp set global autotuninglevel=disabled" (no difference)
4. Hotfix KB931770 isn't really my problem, just slow throughput.

I'm at a loss, I have a Gigabit network that runs at 10Mbps.

I have tried both a Linksys EG1032 v2 and Marvell Yukon 88e8001/8003/8010
NIC with my Netgear GS605 v2 5 port Gigabit switch but it's terrible!

HELP!

There are two registry settings that you can try on a MCE machine. They're described here:

I suggest trying LargeSystemCache=1 and Size=3

Note that the two settings are in different locations -- the locations are described in the linked note above.

Windows desktop OSs don't have the simple UI for this that's available in the server versions (which are mentioned in the note above), but should have a similar result (to some degree). A reboot is generally required for such settings to take effect.

Edit: Vista does have some performance problems at time. I'm not sure if they're related to the hot fix or not. Try testing very large files a number of times to help reduce the chances that you're running into random Vista slowdowns.
