  • I have two machines:
    • one with arch and KDE (installed with pacman -S kde)
    • one with asahi fedora spin (installed with curl https://alx.sh/ | sh and chose the KDE spin)
  • after booting and changing to another TTY with ctrl-alt-f4 and loging in I see vastly different memory usages:
    • arch: 600MB
    • asahi: 1900MB
  • On arch I use sddm and on asahi kde plasma-login-manager
  • Do you have any ideas why the difference in RAM usage is so stark and how I could further investigate?
  • PS.: Normally I wouldn't care about this memory footprint but the asahi hardware only has 8GB of RAM and I had to increase swappiness from 60 to 70 to run thunderbird + firefox + some electron apps.

Did you know that you can list every process running on your system along with their various categories of memory usage?

man ps

Or for a rough idea, just browse them wtih KDE System Monitor.

I prefer htop, but the point is the same - these tools will point to what's using the RAM

Assuming this is a minimal install of Arch, that's kinda the point. Furthermore, I wouldn't be surprised if Asahi isn't fully optimized yet.
