    No nothing like that, I was trying to test 19.10 and using the USB drive so I don't know if that would make a difference

    I think it does! But I do the same thing when trying out a distro, I won't use virtualbox for that. If it's slow Live, it'll be slow installed.

    I will add that that install is in a VM with only 2GB of RAM. From what I have noticed over the years, Ubuntu and others will use more or less RAM at idle depending on how much has been allocated. That is why I mentioned how nice it would be to have documentation explaining how the OS determines this, which would help folks who had questions on it. I am using Xubuntu as my primary on my desktop production machine and laptop used for testing and breaking. I have Debian Buster LXDE on a Netbook running as a server and it is only using 270MB of the 2GB RAM.

    Code:
    ps aux --sort -rss
    Try that. It will list your processes by highest usage from the top down. You can isolate it that way. Found here.

    Look at your actual available ram, not what's used. May be cache load. Linux uses ram like it's supposed to, doesn't let it sit and waste itself.
    was looking for something else, sort of, and saw this topic. i'm using linux mint 19.2 with xfce and this is my memory usage as computer sets right now.

    total used free shared buff/cache available
    Mem: 7.7G 761M 1.3G 33M 5.6G 6.7G
    Swap: 2.0G 0B 2.0G


    surprised as heck to see it only using 761M, but cool as heck. no wonder mint runs so well on everything i've put it on. used to use lubuntu, but that doesn't have nearly all the tools and stuff mint has that are very handy. wouldn't dream of using that bloated ubuntu, even on a very good machine!

    I'm thinking Gnome is where the bloat is, not ubuntu. One of the reasons I dropped Debian Buster with Gnome from my desktop and put ubuntu on it, was because I always kept System Monitor open and constantly saw a lot of gnome stuff that didn't need to be running. Those processes were eating RAM. I installed Xubnutu on it and the difference was very obvious. Much less RAM utilization by background applications. Here's that command on my Xubuntu desktop before and after shutting down my video processing for Motion server and the RAM eater we call Firefox.
    Code:
    urock@urock:~$ free -h
                  total        used        free      shared  buff/cache   available
    Mem:           5.8G        2.2G        719M        112M        2.9G        3.2G
    Swap:          7.8G        512K        7.8G
    urock@urock:~$ free -h
                  total        used        free      shared  buff/cache   available
    Mem:           5.8G        580M        2.5G         17M        2.8G        4.9G
    Swap:          7.8G        512K        7.8G
    Take a look at your buff/cache output.

    Take a look at your buff/cache output.

    I believe you're correct I should have made it more clear. I would say Gnome is the resource hog indeed. On this machine I have Xubuntu all ready to be installed I see how it runs, I had it installed awhile back and its was great. I never really liked Gnome for this reason
