Chrome's "Site Isolation" feature going to consume the system memory!

The newest version of Chrome is going to consume up to 13% more memory of our systems which is an awful thing:(. The reason for this move is the new feature Site Isolation which is added for the security purpose. It encounters the Serious Specture Vulnerability which exposes computers at a chip level. It offers more protection between websites in the back, which consumes more memory for a large number of processes it does.
