title: How much speed is gained with RequireJS/AMD in JS?
body: <p>How much faster is requireJS actually, on a large website?</p>
  
  <p>Has anyone done any tests on the speed of large websites that use asynchronous loading vs not?</p>
  
  <p>For instance, using Backbone with a lot of views (> 100), is it better to simply have a views object that gets loaded with all the views at once and is then always available, or should they all be loaded asynchronously as needed?</p>
  
  <p>Also, are there any differences for these considerations for mobile vs desktop? I've heard that you want to limit the <em>number</em> of requests on mobile instead of the size.</p>
