I also don't understand why every chat app needs 1GB of RAM to itself.
It's already been explained elsewhere, but the cache can be free, as needed - that's how linux works.
There's 57+ GB available ram, yet.

Yip, got that now. I misunderstood, as it's different to Windows, which shows cached memory as free since it's available to apps as needed.

What are you doing?
You don't want to know

ok seriously
I just uploaded 1000 photos to a photo printing website, and have many other SPA websites open. I also have like 20 different applications open that I just keep open for when I want them because I have the RAM for it so why not.

Windows shows memory used for cache as free. Linux per default shows it as used.
Try free -m
Also I would disable swap, it is no longer 2004.

Ah thanks for the explanation!

I'm using Bazzite as of recently, and learnt the first day not to touch the system. Anyway, it's zram not an on disk swap file.

~19 Gb firefox
Tf you doing
The about:processes page doesn't even add up close to that:
Then it's just a bug I guess
Or someone is getting very rich in bitcoin right now
Someone else pointed out cached RAM is shown as used in Linux, so Firefox is probably showing actual usage and the process list probably includes the RAM cached for Firefox.

Does it mean 35.1 GB out of the 44.3 GB is actually cached? Then you have quite low actual RAM usage considering you have 67 GB.
Oh good question. Now I'm wondering. 44+35 is bigger than the 67GB I have, but normally I would expect pretty much all the RAM to hold cached data, where some is also marked as free in case a process needs it.
Can someone explain this memory screen, as your question has raised many more for me!
βCacheβ means space used for disk caching. Itβs free to be used for processes as needed, but the system consumes idle RAM until then to speed things up, so itβs technically not βfreeβ, even though it isnβt used by system processes. In Linux, used - cache gives you the actual consumption by processes.
Thanks, someone else also mentioned this. Cached is considered used in Linux, where as in Windows it's considered free since applications can use it if they need it even though it holds data.
Solution: if you only have 4GB ram, nothing can use more than 4GB
I had one stick of 16GB and it was not enough. I was going to get a second stick, but said screw it and got two 32GB (it's a laptop and only has two slots).

My first thought was that it was running a windows vmβ¦
Nope, I don't have a windows VM at all.
