Due to the Specter issues pretty much everywhere, Chrome will now consume up to 10% more RAM, and there is not much you can do about it.
Google Chorome is known for one thing – its high RAM usage. And starting from today, Google’s web browser will use even more RAM, up to 10% more. Due to all the Spectre vulnerabilities, Google had to make some changes to ensure that everyone has a safe experience online.
In a blog post, Google explained…
Site Isolation is a significant change to Chrome’s behavior under the hood, but it generally shouldn’t cause visible changes for most users or web developers (beyond a few known issues). It simply offers more protection between websites behind the scenes. Site Isolation does cause Chrome to create more renderer processes, which comes with performance tradeoffs: on the plus side, each renderer process is smaller, shorter-lived, and has less contention internally, but there is about a 10-13% total memory overhead in real workloads due to the larger number of processes. Our team continues to work hard to optimize this behavior to keep Chrome both fast and secure.
For some people, this is not an issue, since they have a lot of RAM. However, for those who don’t have the capability of upgrading their RAM, it might hurt performance.
Or just don’t use Chrome, there is also that option.
