Google Chrome has become a lot faster lately

Speedometer 3.0, a new web browser benchmark, was unveiled in March of this year. One of the benchmark's most notable features was its industry-wide collaboration, which ensured that all major browser engines, including Blink/V8, Gecko/SpiderMonkey, and WebKit/JavaScriptCore, would be covered. Google, Mozilla, Microsoft, Intel, and Apple were among those who contributed to its success.

An independent investigation demonstrated the need for a benchmark to test modern websites on different Arm-based SoCs with diverse power. Even an 8-core CPU struggled to load some demanding sites.

Aside from benchmarks like these, hardware capabilities can assist browser vendors optimize and increase the performance of their software, which Google claims to have done. While Speedometer 3.0 was only released this year, Google says development began in May 2022, and the corporation has been utilizing the data to enhance its performance ever since. Google claims a 72% gain in performance from Chrome 101 to Chrome 127, spanning nearly two years.

On a blog post on the Chromium website, it writes:

.. by carefully tracking its recent performance over time as the updated benchmark was being developed. Since the inception of Speedometer 3 in May 2022, we've driven a 72% increase in Chrome’s Speedometer score - translating into performance gains for our users.
