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.

scp only uses compression if you tell it to ('-C' flag). and both ftp and scp involve disk access as part of the test.
If you just want to test your nics, use one of the tools above, like netperf (very simple). It only uses memory (fast), system buses (also fast) and and network hardware. If you get good results, it might be a good next step to try ftp or some file-based test to see if file i/o is the point of slowness.
