Start Render time toggles between 1 and 2.5 second in Chrome browser on Cable

[mbreest]

Hi guys,

I created a couple of test pages and further removed resources and markup step-by-step:
* version with images but no other resources (like css, js) and original html markup has the problem - http://www.webpagetest.org/result/160725_GN_PQ9/
* version with images but no other resources and with head and foot removed does not have the problem - http://www.webpagetest.org/result/160726_GV_EJD/
* version with images but no other resource, with head and foot removed and with further markup reduced and markup bugs fixed does not have the problem and start render starts really as expected http://www.webpagetest.org/result/160726_HR_KKB/

So this problem must be somehow related to our head or foot or something funky in our markup. Strange!

Cheers,
Martin
