Interesting approach.
I'll file this idea for future use.

But in this approach you'll still do not simulate the TCP overhead Ian was referring too.

This is an interesting approach, and is similar to a 'synthetic\application' mix that can be adopted. With this approach the 'application' specific load (which is usually more problematic to reproduce) is generated by a specialized tool for x users doing the more complicated transactions (ie purchases on Amazon etc.). In addition to this load, connections can be open and either (left open) or static files can be browsed to a pattern that simulates the bulk of the other users. The 'synthetic' (or load that is easier to reproduce) load can be driven from a 'cheaper' or 'free' tool. There are also specialised tools 'Frame Thrower' and a tool from 'caw' that will generate synthetic load for hundreds of thousands of users to compliment the 'application' load.

The issue is still the same, this is only a 'model' and whether it can 'predict' real world behaviour will 'depend' on the environment.

Our problem really is that we do not have easy reproducible loads. All our activities are basically heavy (we consider the Amazon ordering process light).
