Very impressive. One cool thing you can further do to improve perceived speed potentially at the expense of some bandwidth is to begin to preload pages when a link is hovered. There are a couple of libraries that will do this for you.

It can shave 100 - 200 ms off the perceived load time, and since your site is already near or below that threshold it might end up feeling like you showed the page before anyone even asked for it.
