Our Commentary ​

JetStream 3.0 is a big deal for anyone invested in web performance. When the major browser vendors — WebKit, Google, and Mozilla — collaborate on a benchmark, you know it's going to be influential. It's a crucial tool for understanding how browsers are evolving and where performance gains are being made. I'm always a bit wary of benchmarks becoming targets rather than tools, but a well-designed, collaborative suite like this helps keep everyone honest and focused on real-world improvements.
