Overview
- Google announced Friday that Chrome hit record scores of 61 on Speedometer 3.1 and 469 on JetStream 3, which the company says make it the top performer in both tests.
- The Chrome team attributes the gains mainly to V8 changes that skip unneeded steps and inline asynchronous 'fast paths' so common JavaScript operations run with less overhead.
- Additional wins came from WebAssembly work that improved SIMD code generation and register allocation, plus Blink renderer fixes that speed HTML parsing, DOM lookups and text processing.
- Those benchmark results were measured on an M5 MacBook Pro running macOS 26.0.1 and are self-reported by Google, so real-world gains may vary by device, OS and site.
- If the changes translate beyond synthetic tests, users should see snappier pages and web apps, and rivals such as Safari could face renewed pressure to match low-level engine optimizations.
