I also don't understand why every chat app needs 1GB of RAM to itself.

MODERATORS
If you got it, flaunt it.
If by "unused" you mean not actively storing data, then the Linux kernel docs disagree.
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).
How does that even happen ππ I have 2x8gb, usually have teams open, Firefox, telegram, a virtual machine with windows 10, a few IDEs and it usually only takes 10-12gb max mostly due to the vm requiring flat 8 gigs

every chat app might use ~1GB because most of them are electron apps, which all spawn their own instance of chromium

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.

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.

Electron apps are bullshit though.
This site says Linux calls cached RAM "free" but in my screen shot it's definitely being shown as "used". I guess this is a choice of this app?

Don't be confused by cached ram, be confused by the oom killer activating while you have plenty of swap and for some reason it kills the shell you ran Firefox from.
If you want to go on a memory allocation adventure try disabling memory overcommit π₯²
If you're out of ram and using swap thats when the oom killer should be killing. Swap is not ram.

~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.

oh i see you're also using a single tab for youtube and no other tabs
Most RAM Linux reports as in used is actually used as disc cache to speed up the IO.
