## AI overview

This article announces Speedometer 3.0, an updated browser benchmark designed to represent modern web applications. Developed through collaboration among major browser-engine teams, it improves score calculation and detail while adding more diverse workloads to guide browser performance optimization and better reflect user experiences.

## Source excerpt

Today's The Fast and the Curious post covers the release of Speedometer 3.0 an upgraded browser benchmarking tool to optimize the performance of Web applications. In collaboration with major web browser engines, Blink/V8, Gecko/SpiderMonkey, and WebKit/JavaScriptCore, we're excited to release Speedometer 3.0. Benchmarks, like Speedometer, are tools that can help browser vendors find opportunities to improve performance. Ideally, they simulate functionality that users encounter on typical websites, to ensure browsers can optimize areas that are beneficial to users. Let's dig into the new changes in Speedometer 3.0. Applying a multi-stakeholder governance model Since its initial release in 2014 by the WebKit team, browser vendors have successfully used Speedometer to optimize their engines and improve user experiences on the web. Speedometer 2.0, a result of a collaboration between Apple and Chrome, followed in 2018, and it included an updated set of workloads that were more representative of the modern web at that time. The web has changed a lot since 2018, and so has Speedometer in its latest release, Speedometer 3. This work has been based on a joint multi-stakeholder governance model to share work, and build a collaborative understanding of performance on the web to help drive browser performance in ways that help users. The goal of this collaborative project is to create a shared understanding of web performance so that improvements can be made to enhance the user experience. Together, we were able to to improve how Speedometer captures and calculates scores, show more detailed results and introduce an even wider variety of workloads. This cross-browser collaboration introduced more diverse perspectives that enabled clearer insights into a broader set of web users and workflows, ensuring the newest version of Speedometer will help make the web better for everyone, regardless of which browser they use. Why is building workloads challenging? Building a reliable ben
