Is it expected for EmberJS to take 200ms for routing to begin and 500ms until it renders?

I have a very small EmberJS project with rather basic templates. I’ve also pre-compiled my handlebars templates, concatinated/minifed my javascript and I’m using ember.prod 1.3. Looking at the webpage test graph over at WebPageTest Test - WebPageTest Details it seems like there’s a rather large gap between the script file loading and the page rendering.

The api.keen.io calls happen inside of the router. The successive image downloads happen once the tags are rendered. The api.keen.io calls are made in a non-blocking fashion.

Is this the expected rendering speed?
