Well, you may have heard about the Specter and Meltdown vulnerabilities, which affect a lot of devices and are difficult to fix. Google by had stated that it had a way of dealing with Spectrum but the thing is not so simple and now an update promises to leave the system more protected.
The company itself explains that to avoid attacks exploiting restricted parts of Spectrum violation memory, it had to create functionality called site isolation. In using it, however, there is a greater consumption of RAM. "The site isolation causes Chrome to create more rendering process, which brings performance offsets.Because of the increase in the number of processes, there are about 10% to 13% of the total memory, "admits Charlie Reis, software engineer at Google
The percentage may not even reach those with more powerful machines, but the intermediate computers, with up to 4 GB of RAM, and those with an even smaller capacity, can feel a lot, especially if there are other applications and several tabs open simultaneously.
If you use the latest stable version of the browser, Chrome 67, is already more secure against Specter, however, you can also feel a little slower because of the isolation of the site, which is embedded in the platform.
"L & 39 site isolation is a major change in the architecture e of Chrome. In Chrome 67, even if an attack via Spectrum occurred on a malicious page, the data from other sites would not generally be loaded in the same process and so there would be much less data available for it. attacker. This greatly reduces the threat posed by Specter, "says Reis.
