Speedometer has been a preferred benchmark tool for Google, known for its real-world reflection of JavaScript performance. The latest iteration, Speedometer 3.0, is now available and brings significant updates to the benchmarking process.
Collaborative Effort for Enhanced Web Performance
Speedometer 3.0 marks a collaborative effort among major browser engines, including Blink/V8 (Google), Gecko/SpiderMonkey (Mozilla), and WebKit/JavaScriptCore (Apple), with Microsoft also contributing. This joint effort aims to create a shared understanding of web performance to improve user experience. The original version was launched by the WebKit team in 2014, followed by a partnership between Apple and Google for version 2.0 in 2018.
What's New in Speedometer 3.0?
The new version introduces improvements in capturing and calculating scores, offering more detailed results and a wider variety of workloads. The benchmarks now include popular frameworks such as React, Vue, Angular, Preact, Lit, Backbone, and Svelte. Additionally, it features an updated set of simulated workloads, including a to-do app, complex web pages, single-page news sites, chart apps, dashboards, and code editors. These enhancements aim to provide a more representative benchmark of web performance.
Simulated Workloads and Their Importance
The simulated workloads in Speedometer 3.0 cover a range of common web applications and scenarios:
- TodoMVC: A to-do application that tests task tracking capabilities.
- News Site: Represents a single-page application (SPA), focusing on static local data without network dependency.
- Charting Apps: Tests SVG and canvas rendering through various chart displays.
- Editors: Focuses on live text editing and form interactions in WYSIWYG and code editors.
These workloads were selected based on their critical impact on user experience, aiming to cover a broad spectrum of web interactions.
Speedometer 3.0 is a step forward in understanding and improving web performance, with contributions from major browser makers. For more detailed information, you can explore the individual blog posts by Apple, Mozilla, and Microsoft on their respective efforts in this benchmarking project.
