title: http request taking too long time waiting for server response
body: <p>We are using 3rd party website monitoring system to see if certain pages are loading well.</p>
  <p>I often see monitor showing up that it took more than 8-9 seconds to load our checkout page as shown picture below:</p>
  <p><a href="https://i.stack.imgur.com/TiSjk.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TiSjk.gif" alt="enter image description here" /></a></p>
  <p>our website is redirecting from non www to www, and then http to https, so I understand couple redirection can happen.  What I don't understand what could be the reason that the page request is taking 2-3 seconds on waiting?</p>
