Errr... establishing an http connection with netscape is a pretty touchy-feeling way to measure speed, and it often involves alot more than just TCP...
Do you have another machine on the network you can http/ftp from and get a reasonable measure of its speed? I use wget and get something like this:
[me:1] caffeine:~$ !wget wget -S http://www.cs.auckland.ac.nz/~pgut001/links.html --04:37:09-- http://www.cs.auckland.ac.nz:80/%7Epgut001/links.html => `links.html.2' Connecting to X:80... connected!

That is, I grab a URL thats cached in a proxy on the LAN. As you can see, the speed I get is pretty unspectacular... I've added debugging code to try and track down why, but as soon as I have more that a certain amount of debugging code in there, the TCP speed increases making the problem hard for me to diagnose....
