• Antergos is eating my RAM like cake


    I’ve been using Antergos for a couple of years now.

    I started facing a RAM eating issue and I have no clue what’s causing it and how to fix it up.

    My system is using Antergos with Gnome and has 16Gb of RAM.

    Whenever I boot, with nothing running, I get like 1.6Gb already filled.

    When I run a browser, Chromium, with a couple of tabs, I easily hit 5Gb RAM and more.

    So, when I use a couple of additional programs, like Sublime Text, occasionally Gimp, and similar web design and development tools, I easily hit the 16Gb bar.

    I’m pretty sure all the things I run shouldn’t take that much RAM. I’ve been using a 4Gb - 8Gb for years without never filling them totally.

    Any thoughts are welcome.


  • @DahmaniAdame Wow!!!

    1- How do you check your free ram?
    2- Maybe, use a task manager to check which applications are causing it?

    I am pretty sure Antergos is not to blame. In fact, Antergos gnome is the most lightweight Gnome I have ever used.

  • @psscnp142 I use both the System Monitor and the command “free” to check the RAM’s status.

    Both give the same result.

    For example, I got 11Gb loaded for running:

    • Chrome with like 15 tabs opened
    • Sublime Text
    • One Open Office document (5 pages of text)
    • Inkscape with a visual with no heavy or complicated design

    Here’s what free returns:

    total used free shared buff/cache available
    Mem: 16386956 11168604 365596 410744 4852756

    I need to investigate further, but I’m not sure where to start.

  • That’s strange behaviour… I have 16GB too and I don’t hit it nearly at all!

    Do you run virtualisation in the meantime?
    What is your filesystem technology? ZFS?
    Do you use ramdisks?
    Also which processes use most of your RAM?

  • You can take a look with:: gnome-system-monitor and click on memory to get sorted by Ram usage…there should be a program/task/ or something causing the high mem use…
    Can you provide also a bootup log for us?

    I’m not sure which one. I used the default setting on the install.

    Also which processes use most of your RAM?

    Chromium and/or Firefox. But it’s not normal to get half of the RAM going to the browser only. I’m quite sure that I used to do the same on 4Gb/8Gb RAM too, but it never took as much as it does now.

  • @joekamprad Here’s the result of the command: https://ptpb.pw/3jwm

    Chromium and its subprocesses take a lot. Here’s a screenshot of my System Monitor:


  • @DahmaniAdame logs show nothing unusual, and no error or fails at all…

    But can you sort system monitor by emory use? to see all heavy load apps?

  • @DahmaniAdame If I’m not mistaken, for Chromium it can be normal to have such memory usage because it opens every tab in a separate process. Firefox bundles it together, like 4 a process or something.

    Are you using an adblocker? It can surely help to increase performance.

    I think the reports of your memory use is quite strange though. It shows 100MB+ each process, but the total not going over 700MB. H4cks?

  • Please read the following: https://serverfault.com/questions/449296/why-is-linux-reporting-free-memory-strangely

    I think it should clear out your confusing and show there’s nothing to worry about.

  • @EarthMind Same happens with Firefox. It eats a bit less, but still, I can’t see a browser with like a dozen of windows locking 5Gb of RAM.

    Yes, I use Adblock, but I think it’s unrelated to the RAM usage.

    And yes, I don’t understand why Chromium loads each tab on +200Mb average.

  • If was is explained on the website of the link I posted, it’s actually good behaviour. One rather would want to prefer RAM to be used to the full, rather than there should be more load on the filesystems.
