Unusual behavior on Chrome - sharma.divyank - 12-22-2015 03:15 PM

I was running wpt for one of the websites on chrome and found this weird behavior in waterfall of same.
It makes only one connection and all requests are downloaded with that connection. In that case how can download be parallel, it should have been sequential.
Can you please help me understand what's happening in this?

Looks like there are actually 2 connections if you look at the connection view: http://www.webpagetest.org/result/151221_QW_9HW/1/details/

The socket connect and TLS negotiation times aren't displayed for the second connection which is probably a result of how we currently get HTTPS timing data from Chrome (actively being worked on so it should be more accurate in a few weeks).
