Unused RAM is wasted RAM. If you’ve got 64GB of RAM but your system never uses more than 8GB of RAM, you don’t need 64GB of RAM and you’re not getting any benefit from it.
On any modern os unused ram is not simply unused. It is used for caching files and other stuff. So more ram can provide significant performance improvements for some taks even if “unused”.
Explain why.

That doesn’t show as unused.
