Optimise red hat 8

[panther]

:p , hy guys
I have installed the red hat 8, but it seems that it absorps all the RAM that I have (256), what should I do? Make modules? How, and, what? Perhaps devises that I never use such as printers, I know that I probably make stupi questions, but sorry, I f someone can suggest something please do so:)

try running the command top in a terminal to see what's using all your RAM. Are you using GNOME or KDE? What's the rest of the spec of this pc?

Try checking 'server services' and stopping functions you don't use

The

free

command will likely show a great deal of the memory is being used for buffers/cache.

This of course is a more efficient use of your memory.
