Last June, Google touted significant performance gains for its Chrome browser and published a blog post detailing how it achieved those gains. Now, almost exactly a year later, the search giant has published a similar post again, continuing to make performance improvements on the Chromium browser.

It’s worth noting that Google isn’t the only company to make such claims recently. Microsoft also recently highlighted a significant improvement in the speed of its Edge browser. Both Microsoft and Google cited the Speedometer 3.0 benchmark for testing.
We also used Speedometer 3.0 to measure browsing performance in our recent review of T-Force DDR5-7200 memory.

Google Reveals Chrome’s New Supercharged Speed
In a blog post, Google said the development team has made significant improvements to memory management and caching. This includes a redesign of the memory layout of many internal data structures used in components such as DOM, CSS, layout, and rendering.
Google said that Blink, the rendering engine in Chromium, now “avoids a lot of useless memory updates” to make better use of CPU caches. In areas of memory handling that previously relied on Oilpan garbage collection, such as the DOM (Document Object Model), the team has expanded this functionality by completely switching from using malloc (memory allocation function) to Oilpan.

Google’s improvements in memory management and caching are crucial to code optimization. As you know, a senior Microsoft engineer recently pointed out similar problems in many applications that slowed down Windows.
String handling inside the renderer has also been improved; the hashing method has been updated to rapidhash, which is said to improve performance. When the rendering task itself becomes time-consuming, such as calculating the CSS styles of various elements, Google added that the caching technology has been enhanced to achieve higher cache hit rates and fewer cache misses.
