Google Chrome ( worlds No1 Web browser ) especially famous for Speed, Performance, Security, Userfriendly interface and more. But for some users its famous for High CPU, memory usage As users report Google chrome causing high CPU & RAM usage. And now With Chrome 67, things just got even worse. As Google has introduced new security feature “Site Isolation” which helps protect you from threats like Spectre and Meltdown, at the cost of using up extra resources.

Chrome Site Isolation Feature
Google described Site Isolation as an “additional security boundary between websites,” and as a way to prevent malicious sites from messing with the code of legitimate sites. The site isolation function is designed to protecting PCs from the known Specter and Meltdown vulnerabilities but will lead to an increase in the RAM used by Google Chrome.
With Site Isolation enabled, such attacks aren’t possible because each site domain runs in a separate browser process which contains data from one domain alone, and not multiple sites at once, at Chrome used to do before Site Isolation. Furthermore, Site Isolation also destroys a site’s process and creates a new one if a user navigates to a different site inside the same tab, keeping isolation at the site-level and not at the tab level, as its name implies.
Charlie Reis, a software engineer at Google, explained:
Site isolation brings a noticeable change to the basics of Google Chrome, but in general, it should not lead to visible changes. Site isolation causes Chrome to create multiple rendering processes, which are accompanied by compromises in terms of performance: the total memory overload of 10 to 13 percent in workloads is due to the greater number of processes involved.
Chrome memory usage will increase across Windows, Mac, and Chrome OS as a result of this change, but Google is working to reduce the impact. “Our team continues to work hard to optimize this behavior to keep Chrome both fast and secure,”
Consume more memory
Google’s site isolation feature is a major change to Chrome. It affects a core part of the browser called the renderer, which turns website programming code into actual pixels on your phone or laptop screen. With site isolation, Chrome splits renderers into separate computing processes more often to wall off data better.
Unfortunately, that means Chrome needs more memory. The increase is about 10 to 13 percent for people with lots of tabs open, Google said in a project document.
Even if a Specter attack arrives on a malicious webpage, data from other websites would not load in the same process and therefore less data would be available to the attacker. This significantly reduces the threat posed by Specter.
Google says that this is just one phase of the Site Isolation project and that it is working on improving the security as well as optimizing the browser to keep it fast and effective. Users should expect some improvements in the coming months, but for now expect some serious RAM usage while browsing through Chrome.
How to enable Site isolation on Chrome
The isolation feature is disabled by default on Chrome, but you can use the following steps to enable it.
Type chrome://flags in the address bar and press Enter.
Scroll down and find Strict site isolation.
Click the Enable button to turn on the feature.
A separate report also suggests Google is working on a Chrome redesign, which has been spotted on Canary for Windows, Linux and Chrome OS. Canary is an experimental version of Chrome where Google adds the latest updates to Chrome before pushing it out to the main browser. As per the reports, the new material design brings a new address bar, refreshed tab shapes and colors, redesigned three-dot dropdown menu, among other things.
