Chrome achieved its highest Speedometer 3 benchmark score with a 10% performance improvement since August 2024, potentially saving users 58 million hours collectively. The improvements came from optimizing memory layouts across DOM, CSS, layout and painting components, enhancing string handling with better hashing algorithms, improving cache utilization for CSS style computation, and significantly boosting font shaping performance. These optimizations target the entire rendering pipeline including HTML parsing, JavaScript processing, DOM manipulation, and pixel rendering.
