On: How html5-boilerplate helped drastically improving our website performance

The transfer time improved by 0.6s (first view) and 0.2s (subsequent view), but the total load time worsened by 9 seconds (first view) and 3 seconds (subsequent view).

What am I missing?

I noticed that as well. After looking at the waterfall chart [1], it looks like Facebook is screwing up the numbers, not anything they can control.

Yeah, but Facebook is loading asynchronously and shows up long after the page has already rendered.
