Chrome RAM Usage Has Increased Because Of Spectre Fixes

Note that Site Isolation increases the memory usage of the browser and that Google mentioned that it has to address known issues that still exist. It's good news for security but as we've seen with other fixes, it'll cost you in terms of system resources. Google's own benchmarks saw memory usage increase by about 10%-13% on the desktop with Site Isolation enabled. Some of the performance hit can be offset by smaller and shorter-lived renderer processes.

Google says that Site Isolation is now enabled for 99% of users on Windows, Mac, Linux, and Chrome OS. Google is holding back the remaining 1 percent to "monitor and improve performance". A website could use such attacks to steal data or login information from other websites that are open in the browser. "As a result, Chrome can rely on the operating system to prevent attacks between processes, and thus, between sites", Google explains.

Site Isolation is enabled in Chrome for Android after the restart. "In Chrome 67 ... even if a Spectre attack were to occur in a malicious web page, data from other websites would generally not be loaded into the same process, and so there would be much less data available to the attacker". For example, cross-site iframes and cross-site pop-ups typically stayed in the same process as the page that created them. However, the Site Isolation feature narrows the scope, limiting each renderer process to documents from at most one site.

When enabled, all navigations to cross-site documents cause a tab to switch processes and puts all cross-site iframes into a different process than their parent frame, using "out-of-process iframes". According to Google, this "also [makes] it possible to block the process from receiving certain types of sensitive data from other sites".

Chicago Cubs must avoid trading for Manny Machado
Machado's four All-Star Game selections are the second-most for any current Oriole , following center fielder Adam Jones (five). Defensively, his.978 fielding percentage is seventh among AL shortstops, while his minus-18 runs saved ranks last.

Google said it's been working on this for several years, independently of Spectre, so the inclusion of Site Isolation was inevitable. You might need to consider using a tab manager extension. "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.

This mitigation was considered necessary as Spectre and Meltdown, as side-channel attacks, require precise observation and manipulation of timers in order to be successfully exploited. However, neither Mozilla nor Microsoft provided any indication when or if site isolation may be coming to Firefox, Edge, or Internet Explorer.
