title: What is Boilerplate code, Hot code and Hot spots?
body: <p>I know these terms are used in context of performance achievement/optimization.  </p>
  
  <p>Recently have been working on that, and have tried searching; but didn't get any example, which clearly elaborate/describe these concepts with the realization of these problems/concepts in real world development scenarios. </p>
  
  <p>Can somebody please thoroughly explain these terms, example scenarios, and where these concepts and terms are likely used.</p>
  
  <p>Thanks. </p>
