Lately, when discussing frameworks, I've been hearing a lot of people refer to some frameworks as being better because they have more advanced usage of OOP, and they "harness the power" of OOP. For me, I've always felt that OOP just helped better organize my work, especially since using a framework. What I'm curious about is if there really is any truth to there being and performance increase associated with using OOP. I'm guessing not, but it's only a guess. Where is the power that these people are harnessing?
