    True story. I remember back in the bad old days when Firefox had notorious memory leaks, so when building my latest PC, I put in 32GB. The monitor app on my desktop has only ever topped out at showing 30% of memory allocated.

    Gives a lot of Space for running Virtual machines.

    Also browsers can chew that up fast if you have a lot of tabs, Firefox has managed to do it a few times. At least until I started limiting its RAM to 8GB (best decision ever)

    Limit Firefox to 8GB of RAM .desktop file
    [Desktop Entry]
    Version=1.0
    Name=Firefox RAM limit 8GB
    GenericName=Firefox Ram limit 8GB
    Comment=Limit RAM for Firefox to 8GB;
    Exec=systemd-run --user --scope -p MemoryLimit=8G firefox
    Icon=firefox
    Type=Application
    Terminal=false
    Categories=Utility;Development;
    StartupWMClass=Firefox
    

    (To use it with other apps like Chrome or Electron apps just replace the command at the end, and startup class with the ones from the program you’d like to run. Icon and Name changes are optional but might be desirable so you remember what app it is for).

      Alternatively you can open about:config and limit memory usage there. For example limit in-memory cache.

      EDIT: it seems firefox doesn’t allow to set RAM limits yet, only cache sizes

        That’s good to know, I don’t know how well it would work though I feel like I enabled something about closing background tabs to reduce memory load (it might have been what you said, it might have been something else I don’t really remember) and it helped a little bit but it still ended up chewing up a lot of memory.

        Setting the limit though did help immediately. And stop the overconsumption problems, occasionally a couple of tabs crash here and there but it doesn’t freeze or worse cause other apps to slow down and freeze. Which did happen before.

        It might be harder for them but there are similar tools that they could use to limit it. One I’ve seen people use is firejail, a tool designed for sandboxing processes and applications.

        I’ve personally never tried it myself though so I can’t attest to how well it works, either for this purpose or sandboxing in general.

      Does it kill Firefox if it tries to go over the limit? I think I tried this once and if there is a memory leak it just closes itself (which is batter than hogging the whole system, bit still)

        No, it just limits the amount of RAM that Firefox (or whatever other application you launch with these parameters) will see.

        A few Firefox tabs may crash occasionally as a side effect. And obviously a Firefox eats up all of the 8GB it’s allocated it may crash itself though usually it doesn’t and tabs will crash before the browser crashes.

          I can confirm this, the first time I tried it out I accidentally set it to 1 GB, Firefox could only see that amount of memory. Though limiting Firefox to only 1GB its a very bad idea and it can cause it to crash it’s not because it’s trying to go over though it’s just because it ran out of memory.

          8GB is what I would consider the safe minimum for web browsing. If you said it lower you’ll have performance losses. Setting it higher though will only chew up valuable System RAM by inactive tabs.

      The other day my laptop was sluggish as hell, checked top and turns out Discord and Orca Slicer were maxing out my cores

        Is Orca that resource intensive? I’m running it in a container with KasmVNC and have never really checked out the resource usage. Admittedly it’s on one of my local servers in another room. I guess it’s how large your projects are too.

        Edit: maybe it’s just my small projects

        What’s the benefit of running Discord’s app instead of just using it as a PWA? A PWA would reuse your existing browser and its session.

            Oh that’s a good point. I totally forgot that Discord has voice features. don’t use Discord often, and when I do, it’s just for text chat. Unfortunately some open source apps I use use Discord for communicating with the developers.

        Firefox unloads old tabs when restarting the browser, so most of those are more like temporary bookmarks.

        Don’t think I’ve ever seen someone open 300 tabs in one session or on Chromium…

    Try realizing ten thousand mesh instances in Blender and watch that sucker eat the rest of your RAM like it’s got a pebble in its shoe.

    I did that on my work PC with 128 GB memory (originally built for esports shit) and it still wasn’t enough.

        It was also supposed to be an all-in-one recording/streaming computer for university events, and they had to use the budget for something. It ended up being used as a proxmox host for a while, then it was handed off to me. Now the most resource-intensive thing it runs is a Windows 11 VM that I torture mercilessly use for experiments. It rarely gets to 10% memory utilization.

            It has an i9 10980, so about 4-5 years old. It was built before I was hired.
