Apple’s WebKit team announced Speedometer 2.0, the update to the “benchmark for web app responsiveness.” Speedometer allows developers to simulate user interactions in web apps.
The web developer ecosystem has evolved significantly since Speedometer 1.0 was first released, as have the trends in what libraries, frameworks, and programming paradigms are used. Developers now commonly use transpilers, module bundlers, and recently-introduced frameworks when creating new sites. This is why, for the last year, engineers from WebKit and Chromium have been collaborating on a new version of Speedometer that better reflects the frameworks, tools, and patterns in wide use today.
Today, we are pleased to announce the Speedometer 2.0 benchmark. We hope this new version of Speedometer helps browser vendors optimize their browser engines for the modern Web.
