Way to edit your post when I was midway through responding :-) We're relatively unconcerned about our website's (home page) source. Our actual application can be seen at https://www.lucidchart.com/demo https://www.lucidchart.com/demo. There you'll see a single large Javascript file served from Cloudfront, plus a few third-party-hosted files that we couldn't reasonably CDN (like Google Analytics and some other third-party APIs). There are also three CSS files. One is the bulk of the data (194KB over the wire) which is sent over the CDN. Then there is a separate file for jQuery UI (which will soon be removed) and one that is shared CSS with other parts of our app.
