It is very difficult to evaluate such things absent of actually doing
simulations of the kind of load you intend to put on your systems.
When evaluating the performance of complex client/server systems, the
devil truly is in the details. You can't be certain of what the
actual bottlenecks will be without having a pretty realistic
simulation of the "production" environment.
After all...
- Your production environment is different from mine.
- Your application is different from mine.
Those factors prevent it from being particularly useful to pretend
that the results I get are in any way useful for you.

It isn't that physicists enjoy physics more than they enjoy sex, its
that they enjoy sex more when they are thinking of physics.
