Chrome is constantly criticized for its memory consumption, and Google is working to address the complaints in recent browser releases for Mac, Windows and Android.
With the latest Chrome version, Google uses its own advanced memory allocator. PartitionAlloc is suitable for low allocation latency, space efficiency and security. It is now used everywhere on Chrome for Android and 64-bit Windows.
In Chrome M89 we see memory savings on Windows – up to 22% in the browsing process, 8% in the version and 3% in the GPU. Even more than that, we improved the browser’s responsiveness by up to 9%.
The browser is also smarter about using and throwing away memory:
Chrome now recovers up to 100MiB per tab, which is more than 20% on some popular sites, by throwing away memory that the active tab is not actively using, such as large images that you scrolled from the screen.
On macOS, Google recently shrank the memory footprint of background tabs by up to 8%, or just over 1 GB on some systems. Tab restriction – of JavaScript timer wake-ups on pages not currently viewed – introduced with Chrome 87 (and widely available in version 88), is also responsible for a 65% improvement in Apple Energy Impact score for pages in the background. This will keep your Mac “cool and keep the fans quiet.”
On mobile devices, Google uses Android App Bundles to optimize level-of-device downloads, and Isolated Splits to load feature splits on demand. This repackaging has resulted in fewer crashes due to resource depletion, a 5% improvement in memory usage, 7.5% faster startup times and up to 2% faster page loads.
Chrome’s 64-bit version on Android 10+ devices with more than 8 GB of RAM has also been rebuilt to offer a more stable experience that is up to 8.5% faster when loading pages and 28% smoother browsing and import delay .
With the latest addition, mobile Chrome starts 13% faster with Freeze-Dried Tabs, or lightweight tabs that are similar to a screenshot, but where you can scroll, zoom in and tap (for links). This version, shown above, is used while the actual tab is loading in the background.
