Besides uncached views (I'm guessing a decent amount of the traffic from HN for this submission would be) you also have to consider parse/eval time. Look at the flame charts in Chrome Dev tools for some of your favorite sites and probably see a few that take almost a second to parse/eval cached JavaScript. It will be even slower for mobile users. Just because it can be cached doesn't mean it's free or even necessary.
