RAM used a lot
Hello,
I am having a problem with the consumption of memory. It is used at about 80%. I have taken a screenshot to show you. While taking the screenshot, only gnome-system-monitor and a terminal (urxvt) were opened.
System:
Mem: 8Gb (total)
cpu: i7 4770k
Thank you very much in advance.

Re: RAM used a lot
As you can already see in the output of "free", ~2GB are actually in use by processes.
Those are easily collected by (next to "only gnome-system-monitor and a terminal") the usual supects, firefox & atom - to a lesser but still significant extent mysql and GDM/gnome-shell. The rest is spread across smaller daemons.
The vast amount or RAM (~5GB) is "used" in caches of which more than 4GB are actually not required and just kept around "in case".
Gnome, atom and firefox are bloated - nothing new about this and nothing exceptional here.

Re: RAM used a lot
Thank you very much for your answer
The problem is that I almost can't use, for example android studio, as I am having random freezes of my whole system, forcing me to completely shutdown my computer, which is really annoying.
So is this normal behaviour ? (with 8Gb of ram)
I completely understand that firefox and atom use a non negligible amount of memory, but it quite seems strange to me. And according to this topic :

Re: RAM used a lot
Android Studio should run OK on 8GB RAM - if you run nothing else... It's a terrible memhog :-(
(Do the pastes reflect the situation after shutting down android studio?)
Kernel halts in response to an OOM condition a certainly a bug, but you should add swap memory and frankly also more RAM for this software stack (you'll also want to run an android emulator which requires 1GB extra) - the "correct" response to an OOM is that the kernel just kills a nasty process - in doubt your IDE with tons of unsaved LoC ...
Atom is basically chromium+node.js 500MB RAM usage are expectable - yes, this sucks.

Re: RAM used a lot
Thank you for your answer .
No, it was a fresh start, so I hadn't even opened Android Studio.
I'll try to add swap memory to see if there's any difference.
Also, I noticed that when android studio and atom were both launched, there was indeed a higher probability for a freeze to happen. (but it doesn't mean that they occurred only when atom was also opened)

Re: RAM used a lot
The (inactive) cache/buffer load is pretty high for a fresh start - probably a tracker (gnome file indexer) run?

Nope, no tracker seems to be running.
