Google, Apple and Mozilla Will Develop a Better Browser Benchmark

The previous version of the benchmark was developed by the Safari team.

Google, Apple and Mozilla are collaborating to develop a better web browser benchmark. Mozilla tweeted about it. Speedometer 3 will be a new test model which that balances the companies' visions for measuring responsiveness.

Unlike some past benchmarks, Speedometer 3 is being started as a cross-industry collaborative effort.
Building this will be hard work, and working together gives us a chance to build the best version to help make the Web faster for years to come. https://t.co/lZyegpIAeW

Speedometer's development policy assumes a flexible decision-making system. For major changes, the consent of all three companies is required, but for "non-trivial changes" the consent of one of the competitors is sufficient. This model of work is designed to speed up the work of the group members and get a higher level of consensus.

Speedometer 2 was developed by Apple’s Web Kit team. The new version of the benchmark is still in its infancy. That’s why a group of developers recommended using Speedometer 2.1 until the project is further along.

Chrome, Safari and Firefox are three of the four most-used browsers today. The last popular browser is Microsoft Edge, but it doesn't run its own engine. It’s based on Google's open-sourced Chromium with Blink.
