From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

jokes aside, you're getting benefits from more caching into ram, and you're also getting the ability to not have to even think about your ram usage, even if the ram isn't actively being used by apps you're getting good use just from having it available, the OS has more wiggle room to use it optimally: I have 64GB of ram and regularly use only about 12-20GB of it, currently 6.1GB is being used as cache
Some apps like Okular (pdf viewer) can be configured to use more ram in the settings, you can set it to be very aggressive about preloading pages so that everything loads faster, set a very high amount of scrollback in your terminal if wanted, etc
I've never done this so I can't speak to how much benefit there is from it, but you can set up a way to preload/cache your most used apps into ram, so that they're always fully loaded and ready to go
