Tumbleweed very slow boot

I’ve been using OpenSuse Tumbleweed for about 14 months now with KDE Plasma. What I have noticed over the past 3-4 months is that the system (boot) is taking so long to boot up with about 3 minutes until the KDE login manager popup and about 1 minute until KDE Plasma loads. With each upgrade the boot time takes longer and longer, I couldn’t find a way to fix it.

Also, when I’m on KDE, some apps sometimes hang for about 20-30 seconds before returning to their normal state.

My tumbleweed version:

$bat /etc/os-release

PS: I’m dual booting with Windows10 and it boots in 30 seconds or less while SUSE 4-4.5 minutes (I don’t have SSD).


First thing to look at is docker. You can either:

a) Disable automatic startup:

$ sudo systemctl disable docker

b) Stop and remove all existing containers

$ docker stop <type every container id here>
$ docker system prune

Thanks for the reply, I disabled Apache, Docker and MariaDB service startup time cut in half but KDE still loads slowly. Is it possible to speed up the startup? I mean what services I can disable without interfering with the OS’s core services.

Check size of journal and reduce it to a minimum. Consider using Storage=volatile. Replacing the HDD by a SSD can result in a large performance gain.
