JetStream 3: A modern benchmark for high-performance, compute-intensive Web applications

JetStream 3 is a comprehensive benchmark for compute-intensive web applications, developed collaboratively by Apple, Mozilla, and Google.

• •Major update after 6 years since JetStream 2, incorporating modern web patterns and WebAssembly specifications like SIMD and WasmGC
• •Focuses on computationally intensive workloads including games, physics simulations, cryptography, and algorithms, complementing Speedometer 3's UI/DOM focus
• •Compatible with browser engine shells like V8's d8, enabling faster developer iteration and more stable testing with less background noise
• •Completely revamped WebAssembly support introducing 12 new workloads covering toolchains including Rust, Kotlin, Java, Dart, and C#
• •Prioritizes real end-to-end use cases over microbenchmarks with diverse frameworks and libraries to prevent overfitting
