Google says the latest Google Chrome release comes with a significant performance boost due to newly added improvements to the open-source V8 JavaScript and WebAssembly engine.

Google Chrome 91, which started rolling out earlier this week, is executing JavaScript code 23% faster with the inclusion of a new JavaScript compiler and the use of a new way to optimize the code's location in memory.

According to Chrome Product Manager Thomas Nattestad, these new enhancements help deliver the maximum possible speed when compiling and executing the JavaScript shipped to the browser by every web page.

Google Chrome 89, released in March, added 8% memory savings in the renderer and roughly 3% in the GPU, also improving the web browser's overall responsiveness by up to 9%. These major memory savings were achieved by optimizing PartitionAlloc, Google's memory allocator, for low allocation latency, space efficiency, and security.

With the release of Google Chrome 87 in November, Google further optimized the web browser performance leading to 25% faster start-ups and 7% faster page loads while also using less memory.

Google Chrome 85 delivered up to 10% faster page loads using a compiler optimization technique known as Profile Guided Optimization.
