DOM Content Loaded - sometimes quick, sometimes slow - les.jones@gmail.com - 02-07-2017 06:38 AM

Sometimes the "DOM Content Loaded" area of the waterfall is skinny and sometimes it's fat. The skinny version always seems to show much better scores on page speed index and start render.

Skinny - 1085 speed index

Fat - 1487 speed index

What makes DOM content loading shorter or faster on the same URL?
