Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Do you have an DSL connection using PPPoE? If so you may try changing the MTU to 1492. If that doesn't work keep lowering it and see if you get an increase in speed. It's a bit of a long shot but it might work.
There's an idea. That might solve something but then again maybe not. I take it you're using the via-rhine kernel module? I googled around and it seems there is some known wierdness with it. I didn't really think it could be the case since it's such common hardware but others seem to be having problems as well. Specifically, they mention slow-downs during high speed transfers (~100Mb/s) which may sound familiar. It seems to happen especially on SMP systems and the theory is that a race condition occurs between the card and the other CPU for hard interrupts. I assume you have a uniprocessor but maybe you have an SMP kernel? The threads I came across also seemed to say that specifying the "noapic" kernel option made this problem go away. I'm not sure what it will do for you since (once again I'm guess that) you have a uniprocessor and therefore have no actual hard interrupts doing anything.
Have a google/linux around for "via rhine nic" (whithout the quotes) to see what I saw.
: Oh and check your /var/log/syslog for any eth0 related errors. Specifically something like "Something wicked happened" or some variant. Many people reported that too.
