Optimizing KDE6 for Memory Consumption

My second computer has only 16 GB of RAM (15.3 GiB) and I need most of the memory for development. I use KDE 6 full installation. Why KDE 6? Monitor switching, sleep, media keys, resolution and scaling configuration, lock screen and sound control. It just bothers me to set it up in light desktop environments.

akonadictl stop

Unfortunately it will start again after restart or login. Will save ~450MiB of RAM.

balooctl disable

I don’t need the indexer, it gets stuck in tens or hundreds of thousands of source files anyways. Will save ~450MiB of RAM.

zypper remove discover6-notifier

For some reason a notifier about the updates consumes 320MiB of RAM…I guess I can live without it.

zypper remove kalendaracc

Will save around 120MiB of RAM. Maybe I should remove the whole Akonadi and Telepathy. I don’t use calendars or IM from KDE, just standard Thunderbird and Gajim. Because KDE programs change all the time, new project, new names, less features. I used Kopete from KDE3 a lot.

This way the base system in Wayland will consume around 2.1GiB of RAM.
