Google Chrome has long been considered a scary Ram in the browser world. Just open several tabs in chrome at the same time and you will experience problems such as slowdown, lag, and freeze. This is also the biggest weakness that makes this browser receive heavy criticism from the user community.

Over the years, Google engineers have had to work hard to overcome this problem step by step. In the latest effort, the Mountain View company confidently announced that the latest version of Google Chrome just released has integrated the ability to save more optimized RAM on the Windows system, and at the same time, significantly improved. power consumption as well as the overall responsiveness of the browser.

The new Chrome update that Google mentions is Chrome 89, which launched earlier this week. This update comes with a bunch of important improvements in the ability to manage system resource usage, specifically Chrome’s RAM on Windows. Google’s internal testing shows that the browser now targets up to 22% less RAM on Windows than before.

Chrome is known for its ability to “eat” RAM

More specifically, according to Chrome Product Director Mark Chang, the new version also “proudly” saves up to 8% memory in the renderer (render) and about 3% in the GPU.

We achieved this by using PartitionAlloc, an advanced memory allocator developed by Google, optimized for low allocation latency, capacity efficiency, and security.“, Explained Mr. Chang.

Before applying to Chrome, Google used PartitionAlloc for a while to test Blink’s RAM management, the company’s internal browser rendering.

Google says that the same RAM savings achieved in the latest version of Chrome are primarily rooted in improvements to browser tab memory management, reducing the amount of RAM required by up to 8% (max. to 1GiB).

Chrome now regains up to 100MiB per tab – that’s more than 20% on some popular sites – by removing memory that the background tab isn’t actively using, such as large images that you’ve scrolled out of the box. screen“, Mr. Chang added.

Not only on Windows, Chrome’s system resource consumption on macOS and Android is also gradually improving. At the same time, the page load capacity and boot time have also been optimized faster.

For example, Google improved overall web browser’s responsiveness by up to 9% and achieved a 65% improvement in Apple Energy Impact scores for background tabs.

With the release of Chrome 87 in November 2020, Google has also significantly optimized the browser performance, making startup 25% faster and loading 7% faster pages while using less memory.

Before that, Chrome 85 also comes with page loading up to 10% faster thanks to the presence of a new compiler optimization technique called Profile Guided Optimization (PGO).

Saying so to see that Google has been really serious about improving, optimizing and turning Chrome into a more comprehensive tool. Although this process is not fast, but “slow but sure” is what users expect!
