Site Isolation in Google Chrome v67 Increases Ram Use by 13 per centByNitish Singh-July 12 2018.757 Figure 1 Photo Courtesy of Lam Sao Devao Charlie Reis from the Google Chrome Site Isolation team revealed “Site Isolationis a major change to Chrome’s architecture that restricts each renderer process to documents from a single site.

The functionality won’t soon make it into the app’s mobile version as Google has yet to figure out a way to prevent excessive use of memory on mobile phones and tablets. Google Chrome v67 was also found to contain the recently patched Download Bomb bug via a security update. Grip.
