High memory usage (1,3Gb+ after login)

pedrofleck · 2015-11-08 23:01:57

Hello,
Recently (a few months, actually), my computer is using a lot of RAM, after I log in it is using around 900mB and then it goes to 1,3~1,6Gb; it isn't a big deal because I have 8Gb (no swap), but using a lot of webapps and tabs, plus LibreOffice my computer freezes very frequently and I don't know what is causing it.
Here's the output (only Epiphany open with 3 tabs and gnome-terminal with 2 tabs open):

free -m
              total        used        free      shared  buff/cache   available

Swap:             0           0           0

What do you mean by 'after I log in' - what applications do you start automatically?
Memory use seems to be OK, the applications you use take up a bit of RAM.
Next time when you experience freezing, check memory use, cpu use etc.

Which DE/WM are you using? KDE is quite guzzler on memory. Looks like it might be gnome.

karol:
Just Gnome-Pie and Geary (that uses a lot of RAM, I know, but not that much), when it freezes it's because of full RAM

nomorewindows:
I'm using Gnome Shell (v. 3.18)

I don't see any problems, it's all accounted for in the output of top, if you thing that ram usage is too much you have to use programs that use less.

On the other hand it's not clear if you know what makes libreoffice freeze or not, in the OP you say you don't but in the reply to karol you say something about full ram, this means you either have to buy more ram or start using swap.

You mean all 8 GB are used? Please do check (and post) the output of 'free' next time.
Anything interesting in the logs or systemd's journal?
