Apple achieves remarkable 60% boost in Safari and WebKit performance

The improvements follow the introduction of Speedometer 3.0 in March, a collaborative effort by Apple, Google, and Mozilla aimed at advancing web performance.

Speedometer 3.0, a new browser benchmark, offers detailed insights into web performance, allowing developers to create faster and more efficient websites and web apps. Apple reports a remarkable 60% enhancement in Safari's Speedometer 3.0 score between Safari 17.0 and Safari 17.4, achieved through a series of optimizations implemented over several months.

The optimizations, ranging from subtle improvements to major enhancements, have culminated in Safari 17.4 being approximately 13% faster than Safari 17.0 on Speedometer 2.1 as well. These advancements empower developers to build more responsive and snappier web experiences than ever before.

An extensive blog post by Apple's WebKit development team focuses on the technical intricacies of the optimization process.
