title: How does the memory footprint of some common web framework(s) compare?
body: <p>Hypothetically, if I were to build the same app using a few popular/similar frameworks, say PHP(cakePHP|Zend), Django, and Rails, should the memory consumption of each be roughly the same?</p>
  
  <p>Also, I'm sure many have evaluated or used each and would be interested in which you settled on and why?</p>
