 """Apple's Speedometer performance benchmark.
 
 Speedometer measures simulated user interactions in web applications.
 
 The current benchmark uses TodoMVC to simulate user actions for adding,
 completing, and removing to-do items. Speedometer repeats the same actions using
 DOM APIs - a core set of web platform APIs used extensively in web applications-
 as well as six popular JavaScript frameworks: Ember.js, Backbone.js, jQuery,
 AngularJS, React, and Flight. Many of these frameworks are used on the most
 popular websites in the world, such as Facebook and Twitter. The performance of
 these types of operations depends on the speed of the DOM APIs, the JavaScript
 engine, CSS style resolution, layout, and other technologies.
