What is Speedometer?

Speedometer is a benchmark for web browsers that measures Web application responsiveness by timing simulated user interactions on various workloads. Our primary goal is to make it reflect the real-world Web as much as possible. When a browser improves its score on the benchmark, actual users should benefit. In order to achieve this, it should:

  • Test end-to-end user journeys instead of testing specific features in a tight loop. Each test should exercise the full set of what’s needed from the engine in order for a user to accomplish a task.
  • Evolve over time, adapting to the present Web on a regular basis. This should be informed by current usage data, and by consensus about features which are important for engines to optimize to provide a consistent experience for users and site authors.
  • Be accessible to the public and useful to browser engineers. It should run in every modern browser by visiting a normal web page. It should run relatively quickly, while providing enough test coverage to be reflective of the real-world Web.
