The only way to really simulate real-world traffic would be to alter
lag times, have percentages of simply dropped tcp connections, malformed
packets, etc.
The only way to do this right is to alter the testing machine's tcp stack
behavior in the kernel, or run the test through some specialized hardware
designed to introduce these abnormalities (this hardware does exist).
Nistnet attempts to do this in software and is the best i've seen so
far at this. It involves a linux kernel patch, however.
The short of it is, that real world testing is either very
difficult (impossible with a tool like ab) or very easy (put the
machine in actual real-world production). :) The only way I would trust
someone's lab network benchmarks is if they could show a correlation
between their benchmark loads and real-world loads on production machines.
This is something I'm working on right now.
