I will wholeheartedly agree that a firewall isn't a magic box that will make you secure. It's a necessary, but not sufficient, requirement for being secure. And, it needs to be done with everything else in mind.
My entire point is that you separate your servers for security-based reasons, not performance ones. The performance reasons are usually non-existent.
