Exactly, people in this thread missing the point of the use of RAM. A perfect operating system always going to use as much RAM is available for caching and there are long running processes that can be swapped out to free RAM for more important use cases. Memory management and paging/swapping is an interviewing topic for SREs/systems engineers, and this is not an accident. Oversimplifying the problem does not help.

I was just told last week about how caching static (!) files from web server in redis increase performance in their infrastructure. I was baffled.
