title: How many Requests per Minute are considered 'Heavy Load'? (Approximation)
body: <p>Often times people talk in their (optimization &amp; performance related) questions and answers about 'heavy load'. </p>
  
  <p>I'm trying to quantify this in the context of a regular web application on a typical server (take SO &amp; its fairly small infrastructure as example) in a number of Requests per Minute, assuming that they return immediately (to simplify and take database speeds etc. out of the equation).</p>
  
  <p>I'm looking for a nominal number/range, not 'where the CPU maxes out' or similar. A rough approximation would be great (e.g. >5000/min). Thank you!</p>
