Introducing the JetStream 2 Benchmark Suite

BRANK

Today we are announcing a new version of the JetStream JavaScript benchmark suite, JetStream 2. JetStream 2 combines a variety of JavaScript and WebAssembly benchmarks, covering an array of advanced workloads and programming techniques, and reports a single score that balances them using a geometric mean. JetStream 2 rewards browsers that start up quickly, execute code quickly, and run smoothly. Optimizing the overall performance of our JavaScript engine has always been a high priority for the WebKit team. We use benchmarks to motivate wide-reaching and maintainable optimizations to the WebKit engine, often leading us to make large architectural improvements, such as creating an entirely new optimizing compiler, B3, in 2015. JetStream 2 mixes together workloads we’ve been optimizing for years along with a new set of workloads we’ll be improving for years to come.When we released JetStream 1 in 2014, it was a cross-cutting benchmark, measuring the performance of the latest features i…
