title: How to minimize response time for requests
body: <p>I've been using CakePHP for a while now. It is very easy and great to work on projects of wide range. I've been doing most of heavy calculations and database access in controller function. And only using the views to display the data which user is interested in. It has been working great till now. And no problem has occured. 
  But I want to ask is that, "Is it a right way to work with a framework in PHP. Is there any other way i can minimize the time required to process the request.
  Thank You.</p>
