This sounds suspiciously like a mismatched duplex issue, not a SNP issue. Are there errors occurring on the interface?

In the IP Chimney thread there was a link to an article that alluded to more general issues with Broadcom drivers in Win2k3. I'm seeing some issues with a Dell PE2950 that we recently put into service as a web server. I first set the sysetem up using Windows Server 2003 x64 and had serious network throughput problems. Even on the local network (100 Mbps switch) I was seeing no better than about 130 kbps throughput. This was (and still is) without the TOE enabled. I farked around with it, trying different drivers until I finally gave up and installed Win2k3 32-bit. Much better network speeds. But what I'm seeing is now is an occasional hiccup where a web page appears to take several seconds to load. This is actually a little reminiscent of the original problem, as it would appear that the network would experience varying speeds, with short periods of a couple seconds that were extremely slow. Looking at the page generation speeds, it's not the web or application server, as the pages take just a fraction of a second to generate. Everything points to continued networking problems. Web sites from other servers in the same web farm don't display this behavior, so it would seem to be something with the PE2950 and not the network itself. Anyone else seeing something similar? Suggestions for either a fix, or where to begin troubleshooting would be appreciated. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~ ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
