title: DOMContentLoaded very slow in Chrome
body: <p>I have a complex ASP.NET page, portal type, containing multiple sub-modules.
  Some are classic ASP.NET user controls (with server side logic), while other are pure client-side (kendoui / jquery / ko / webapi).</p>
  
  <p>The problem is the page loads very slow in Chrome.
  Checking its timeline in Chrome Dev Tools I see DOMContentReady is fired after almost 1 min, while first paint starts after about 11 s.</p>
  
  <p>The same page loads in FF in about 20-25 s, which is normal (giving page complexity).</p>

  <p>Any idea what is causing this and how can it be fixed?</p>
  
  <p>Thank you</p>
