title: WCF - Handling request from multiple clients
body: <p>My WCF service library is hosted as a Windows Service and is supposed to handle requests from multiple clients.
  One request that clients are going to make frequently is pretty resource intensive.</p>
  
  <p>I have two doubts pertaining to above scenerio:</p>
  
  <ol>
  <li>How a WCF service handles multiple client's request?</li>
  <li>Is there any WCF configuration to make the process efficient?</li>
  </ol>
  
  <p>Thank you!</p>
