Instead, Spedometer is used to measure the responsiveness of the Web browser and to measure the browser DOM API The speed, the efficiency of the JavaScript engine,CSS Style resolution and layout performance.

Google Chrome Browser indicates that, since the beginning of 2026, the Chrome Browser has risen 10 per cent on JetStream and finally scored 469 points. The Chrome Browser Spedometer's latest score of 61 is 5% higher than the score of about 1 year ago.

At the JavaScript level, Chrome focused on the acceleration of common paths. The team links more " fast paths " in an optimised compiler, allowing the engine to jump over unnecessary steps, with a focus on differentiating, micromission distribution, await resolution, data sorting and string comparison.

With regard to WebAssembly (page compilation), Chrome continues to enhance the capacity of V8 to handle high load tasks.

The team optimized the internal data structure, the SIMD (single-directive multidata) command code generation and the distribution of the register, resulting in a more visible acceleration of scenarios such as AI, password and interpreter.

In the Brink Rendering Engine section, Chrome optimizes font layout and SVG graphic rendering.
