The latest development in the web ecosystem is the release of JetStream 3, a benchmarking tool created in collaboration with Apple, Mozilla, and other partners. This new version aims to improve user experience and real-world performance by providing browser engineers with a clear target to optimize their efforts.
Benchmarking plays a crucial role in identifying performance regressions and motivating browser engineers to prioritize optimizations. It also fosters healthy competition among different browser engines, ultimately benefiting the entire web ecosystem.
JetStream 3 is the result of a collaborative effort among major browser engines, following a strict consensus model for adding new workloads. This open governance approach ensures that the benchmark serves the best interests of the web ecosystem as a whole.
The decision to update JetStream was driven by the need to stay current in a rapidly evolving technology landscape. With the last major release, JetStream 2, dating back to 2019, it was time for a refresh to reflect the latest advancements in web technologies.
JetStream differs from other benchmarks like Speedometer by focusing on computationally intensive tasks in web applications, such as browser-based games, physics simulations, cryptography, and complex algorithms. It is designed to run in engine shells like V8’s d8, allowing for quicker iteration and more stable testing.
The selection of workloads for JetStream 3 involved balancing microbenchmarks with real end-to-end use cases. Diversity and practical considerations like completion time, memory usage, and network requirements were key factors in choosing workloads for the benchmark suite.
One of the significant updates in JetStream 3 is the increased focus on WebAssembly (Wasm). The benchmark now includes new Wasm workloads representing a variety of tasks generated from different programming languages like Java, Dart, Kotlin, Rust, and C#.
The inclusion of new JavaScript workloads in JetStream 3 better reflects how JavaScript is used in real-world applications. Workloads like Babylon.js, bigint-noble-ed25519, and prismjs provide a comprehensive assessment of JavaScript performance in various scenarios.
JetStream 3 also introduces updated versions of existing JavaScript workloads, such as WTB and Sunspider, to ensure the benchmark remains relevant and reflective of modern web development practices.
In conclusion, JetStream 3 represents a significant advancement in browser benchmarking, providing valuable insights for browser vendors and users alike. The collaboration between major browser engines and the continuous evolution of benchmarks like JetStream, Speedometer, and MotionMark contribute to ongoing improvements in browser performance.
If you’re interested in contributing to the JetStream benchmark or have suggestions for further enhancements, you can join the repository on GitHub. Stay tuned for more updates and improvements to these benchmarks in the future.
