Howcome refreshing my web app with F5 is extremely slow and hangs, while hitting enter on the address bar refreshes the page instantly?
<p>I have a web page which uses in PHP and a jQuery DataTable to show data from a database.</p>

<p>When I enter the URL and hit enter, the page loads instantly, and I can do this repeatedly and the page keeps loading instantly.</p>

<p>However, when I hit F5, the page goes blank and hangs, it is trying to load the page but is just too slow.</p>

<p>What would be causing this?</p>
