I have 32GB and regularly fill both that and my swap space to the point where my system freezes up and i have to restart.

i am quite tabby though. And vscode has become quite a memory hog and i usually have several of those open too as i work across different projects

You use Chrome for everything including writing code and notes. Different outcome was unexpected really.

well, i use firefox for my browsing but yes i get your point

I have this misunderstanding even if I use Linux a lot that when I work for a long time with a lot of things opened… my RAM fill up and never get down.

I heard it had to do with swap, can you quickly explain why?

Its more likely caching. They just keep the cache of files opened earlier so that its ready for you if you need it immediately again. Also unused ram is wasted ram

Its more likely caching.

Pagecache doesn't count towards used ram.

Also unused ram is wasted ram

Uninstall ram sticks to not waste them.

Yes it won't count used ram. But the other person has a "feeling" that linux uses the same ram even when he quit the apps. So that may count.

Use RAM efficiently. There is no point in freeing all ram

There's no benefit in having RAM sitting idle and empty. Si Linux caches a lot of things.

You might benefit from installing earlyoom. It'll kill some of your processes before the system freezes from running out of memory.

Appreciate this. I have a Chromebook running Garuda with only 4gb of RAM, and if I get too much going the system locks up. This might help it handle things better.

thanks, i'll take a look.

I was getting to the point of writing something for it
