Mind, GeoServer out of the box won't perform that well, some tuning is
needed.

Just grab the tool I attached in the first mail of this thread,
you'll be able to make it generate whatever csv you need and
find tune other parameters as well such as the map area.
You can find some usage instructions in the thread titled
"Chat about the load testing setup".

As for the test, not sure we can make this many runs, in the
end we need to stick everything in a 20 minutes presentation
(which is more than just shooting at the audience comparison
charts, we'll also need to make some HP on why the results
are different).

Cheers
Andrea
