screen shot of memory usage by app, showing Firefox using over 18GB of RAM

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

    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!

        “Cache” means space used for disk caching. It’s free to be used for processes as needed, but the system consumes idle RAM until then to speed things up, so it’s technically not “free”, even though it isn’t 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.
