title: Chrome network Timing , how to improve Content Download
body: <p>I was checking for XHR calls timing in Chrome DevTools to improve slow requests  but I found out that 99% of the response time is wasted on content download even though the content size is less than 5 KB and the application is running on localhost(Working on my local machine so no Network issues).</p>
  
  <p>But when replaying the call using Replay XHR menu, the Content download period drops dramatically from 2.13 s to 2.11 ms(as shown in the screen shots below). Data is not cached at browser level.</p>

  </ul>
  
  <p>Can someone explain why the content download timing is slow and how to improve it?</p>
  
  <p>The Application is an ASP.NET mvc 5 solution combined with angularJS.</p>
  
  <p>The Web Server Details:
   - Windows Server 2012 R2
   - IIS 8</p>
  
  <p>Thank you in advance for your support!</p>
