I'm a little confused. How much of this is client-side optimization-specific? It seems like most of these (if not all) are also standards in making your server-side rendering apps faster as well. For example minifying, CDN, GZip, etc. would all be used in a Rails app, not to mention a bunch of these come by default with Rails. If I'm not mistaken, a bunch of the speed problems with the client-side apps has to do with memory leaks (not addressed) and client-side browser speed (not really addressed). I was wondering if there are any solutions to these. In any case, good article, was pretty helpful.
