The feature looked to improve stability, while making the internet browser more resistant to attacks such as Spectre. It's good news for security but as we've seen with other fixes, it'll cost you in terms of system resources. Google believes there's a 10 to 13 percent memory overhead compared to earlier versions since it'll need to run processes for each site. Some of the performance hit can be offset by smaller and shorter-lived renderer processes.
If you've noticed that Chrome on the desktop is using more RAM, you're not imagining it. Google has enabled a Site Isolation feature in Windows, Mac, Linux and Chrome OS to help mitigate against the Spectre vulnerability - and it's a bit memory-hungry. It has held back one percent to monitor performance. With Chrome 67, things just got even worse.
The mitigation is an impressive engineering feat that's created to lessen the damage of attacks that exploit a new class of vulnerability that came to light in January.
As you may recall, such attacks use the speculative execution features of most processors to access sections of memory that should be off-limits to a piece of code.
Following the disclosure of the Spectre and Meltdown vulnerabilities, browser vendors have been in the hard position of balancing mitigations for these hardware-level vulnerabilities with preserving browser performance.

According to the CBC, Canada will spend 1.23 percent of its GDP on defense in 2018, down from 1.36 percent a year ago . With all, Trump believes the U.S.is getting "ripped off" in an unfair marketplace.
"This means all navigations to cross-site documents cause a tab to switch processes". The first uses of out-of-process iframes shipped previous year to improve the Chrome extension security model. "This significantly reduces the threat posed by Spectre".
Tip: Firefox supports a similar feature called First-Party Isolation. CORB tries to transparently block cross-site HTML, XML, and JSON responses from the renderer process, with nearly no impact to compatibility.
"Site Isolation is a significant change to Chrome's behavior under the hood, but it generally shouldn't cause visible changes", Google's Charlie Reis explains.
Spectre breaks the isolation between different applications and allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. To date, most others have disabled the same types of precise timers as Chrome.
