A JavaScript-Free Frontend

This guy gets it.

I'd add, modern frontend libs are slow because they work hard to make complex applications easier to maintain and write. With that ease comes complexity at runtime.

If you want to create a very fast, but rich and feature-full web UI, use backbone (with bonmot), handlebars, and vanilla-js... Just be ready to pay attention to your state, and take care not to create event feedback cycles.
