Apple Releases Speedometer 2.0 Benchmark

Apple has announced the release of Speedometer 2.0, a benchmark that tests a browser’s Web app responsiveness by timing simulated user interactions.

In 2014, the WebKit team at Apple released Speedometer 1.0, a benchmark for web app responsiveness. It simulates user interactions in web applications, using TodoMVC to orchestrate adding, completing, and removing todo items. Speedometer repeats these actions using DOM APIs that were extensively used in real-world applications. The performance of these kinds of operations depends on the speed of the JavaScript engine, DOM APIs, layout, CSS style resolution and other parts of the browser engine.

Browser engineers have been optimizing their engines using Speedometer as a proxy for real-world use of popular frameworks for a number of years. Originally, Speedometer included implementations of todo apps in six popular JavaScript frameworks and libraries in heavy use: Ember, Backbone, AngularJS, jQuery, Flight, and an early version of React. It also included vanilla JavaScript.
