Chrome: Google is working on the engine
Google Chrome is reaching new speed records through profound technical adjustments. Special optimizations in the processing of scripts and image display are intended to noticeably speed up daily surfing in the browser.
New best values in benchmarks
Recently, Chrome has been in the headlines mainly because of bugs, long-standing unpatched security holes and large AI downloads. Now, however, there is once again more positive news about Google’s browser. The program has set new records in some performance tests. On a MacBook Pro with the current M5 processor and MacOS 26.0.1, the software achieved a score of 61 points in Speedometer 3.1. This corresponds to an increase of five percent compared to the previous year. In the JetStream 3 test, the result improved by ten percent to 469 points since the beginning of the year. These two benchmarks are established testing procedures that are maintained in collaboration by developers such as Apple and Mozilla. They precisely measure how quickly web applications respond and how efficiently complex tasks are processed. For end users, Chrome’s new highs mean smoother loading of websites in everyday life. However, one disadvantage remains the traditionally high amount of RAM required by the browser to achieve the level of performance achieved.
Optimizations under the hood
Like Google in one official blog post reported that the developers focused primarily on the V8 engine when optimizing. The element processes JavaScript. By skipping unnecessary execution steps in common routine tasks, the engine now works much more efficiently. In addition, the team has adapted the heuristics that decide when a program code is optimized. Since such an optimization itself costs computing time, the browser will now better consider whether the effort is worth it. This particularly benefits asynchronous tasks that run unnoticed in the background while the user is already reading text on the page or watching videos. At the same time, the programmers revised the way they use WebAssembly, which is often used in computing-intensive applications such as artificial intelligence, complex browser games or cryptography. The data exchange between JavaScript and WebAssembly is now more direct, as redundant data type conversions are no longer necessary.
Faster page loading
The Blink engine, which calculates the actual image structure of websites, also received a comprehensive update. In order to process HTML documents more quickly, the software will in future use so-called SIMD operations. A single command processes several data sets at the same time, which is reminiscent of how modern graphics cards work. This noticeably speeds up the copying of character strings during the initial loading process. In addition, a more intelligent cache reduces the workload on RAM when processing the document structure. The developers reduced the memory requirement for basic page layouts, which should particularly help on weaker computers and laptops. Other adjustments include Apple Advanced Typography’s faster calculation for fonts, a new cache for complex vector graphics, and increased security through isolated data structures.
