Google today announced that its Chrome browser has received the “highest score ever” in the Speedometer 3 benchmark. Speedometer 3 is designed to measure browser performance and was developed by Google, Apple, Intel, Microsoft, and Mozilla.

The test is designed to measure web responsiveness through a variety of workloads such as HTML parsing, JavaScript and JSON processing, pixel rendering, CSS applications, and more.

The optimizations Google has implemented over the past year have resulted in a 10% performance boost since August 2024, which Google says will result in a better browser experience for end users.

The team made significant improvements to the memory layout of the DOM, CSS, layout, and many of the internal data structures in the drawing component. Blink now maximizes CPU cache utilization by keeping state where it belongs based on access patterns, avoiding a lot of unnecessary system memory waste. Internal memory in Oilpan, which originally relied on garbage collection, such as DOM, has been expanded by converting types from malloc to Oilpan. This usually speeds up the affected area because it does a good job of packing the memory into Oilpan’s backend.

On the M4 MacBook Pro with macOS 15, Chrome 139 scored 52.35 in benchmarks. For more details on the new optimizations, see Google’s blog post.

Apple hasn’t recently shared its maximum Speedometer 3 test results for Safari, so there’s no direct comparison, and it’s worth noting that Google seems to be using the Speedometer 3 instead of the newer Speedometer 3.1 test.
