If you have 0B’s total enabled, not to be confused with used, then I’d recommend either enabling zswap or zram. zram compresses only ram and zswap compresses ram and then moves it to the drive as needed. Enabling one will improve your experience in general as currently your system just will try to shove everything in ram until it is full and need hard reset.

See [https://wiki.archlinux.org/title/Swap#Swap_file](Arch Wiki Swap) and [https://wiki.archlinux.org/title/Zswap](Arch Wiki zSwap)

It will still be faster than hitting the drives, whether that is a hard drive or nvme ssd. The compression code is highly optimized.

What “background services” breaks down to is things like the desktop. In the system monitor you can see a breakdown of what that is if you click on “show details sidebar” in top right. On my system for instance, plasmashell and kwin combined(the interface) is taking 700mb. Without the info from the sidebar it is harder to give advice.

Baloo is used for searching you system for files including contents. You can disable it if it isn’t something you’d use, limit it to certain directories or limit it to file names only. It will be under search in settings.

Edit: Also check how much swap you have enabled in the system monitor overview. You might look into turning on zram support if it isn’t already enabled which will compress ram as needed which might improve your experience.
