KDE Neon slower boot time than Debian Buster

Hi!
It takes KDE Neon 24 seconds to boot. Debian does it in 8 seconds. This is on the same computer and both installs is on SSD's.

Debian Buster:

This is no criticism, I just wonder why KDE Neon (Ubuntu) is slower?

KDE Neon is a perfect distribution for me with low memory (RAM) usage and a setup that meets the basic needs (to avoid installing many applications I won't use by default).

But... the problem is that KDE Neon is too cumbersome to boot (slow boot and shutdown times). This situation is very annoying. I hope there's a cure for that as soon as possible.

Have a good day, have fun.

Maybe irrelevant with your case, but mine also used to boot so long after upgrading from Xenial to Bionic. Turns out it was due to something about outdated initramfs' resume file for swap uuid (https://askubuntu.com/a/1034952/847385). The solution mentioned in that answer fixed it for me (more details about the issue can be seen in the linked bug reports). Booting time has gone down to less than 10s ever since (that includes typing in my password after the prompt appears to finally seeing the desktop interface).

Hello,

First of all thank you for the suggestion. /etc/initramfs-tools/conf.d/resume does not have this file ...

KDE and KDE neon developers should address this issue and produce solutions.

Have a good day, have fun.

Hi,
Can you post the output of the following command in the blog?
It would be useful in order to compare both Debian and KDE Neon, maybe they have differences on the services managed at the startup.
I noticed you use systemd-analyze plot to show the results.

Not sure how much of an issue this is. It would be subjective to hardware. On a Xiaomi Notebook (12.5 Air with Core M3) it boots in about 8 to 10 seconds. On my Ryzen desktop and Lenovo Y410p it boots in about 12 seconds. But both of those throw a post and logo screen into the mix.
