JetStream 3, a new benchmark tool for web browsers, has been released in collaboration with Apple, Mozilla, and other partners. This benchmark tool is designed to measure the performance of computationally intensive tasks in web applications, such as browser-based games, physics simulations, cryptography, and complex algorithms.
Benchmarking is essential for browser engineers to catch performance regressions and prioritize optimizations. JetStream 3 is the result of a collaborative effort across major browser engines, with a focus on open governance and consensus building. This ensures that the benchmark serves the best interests of the overall web ecosystem.
The previous version, JetStream 2, was released in 2019, making it ripe for an update. With the rapid evolution of web technologies, benchmarks need to be updated to reflect real-world performance accurately. While Speedometer 3 focuses on UI rendering and DOM manipulation, JetStream 3 targets computationally intensive tasks.
One significant update in JetStream 3 is the increased focus on WebAssembly (Wasm). The benchmark now includes new workloads that cover a wide range of applications generated from Java, Dart, Kotlin, Rust, and C#. This shift reflects the growing importance of Wasm in modern web development.
The benchmark also includes new and updated JavaScript workloads that better represent real-world usage. These workloads cover a variety of tasks, from 3D rendering to server-side rendering and compilation speed. The inclusion of these workloads ensures a more comprehensive assessment of browser performance.
JetStream 3 aims to provide a clear view of browser performance for both vendors and users. By continuously iterating on the benchmark and incorporating feedback from the community, the developers behind JetStream are committed to improving the tool for the benefit of all users.
If you are interested in contributing to the benchmark or have suggestions for improvement, you can join the repository on GitHub. The team behind JetStream is dedicated to making continuous updates and enhancements to the benchmark tool.
Overall, JetStream 3 represents a significant advancement in browser benchmarking and provides valuable insights into the performance of different browser engines. Alongside other benchmark tools like Speedometer and MotionMark, JetStream helps drive healthy competition and improvements in web performance.
