Execution times of the install steps

> 2022-11-14 07:53   6558  1.14.55  sudo zypper dup -l

2022-11-14 07:53:54 - zypper start
2022-11-14 07:55:14 - install start
2022-11-14 08:18:17 - install end

So we have less than 2 min. for solving and downloading 184 packages.

23 min. for installing the packages, BUT only 2 actions took long:
- 9 min for installing kernel-default-5.14.21-150500.34.1.x86_64
- 8 min for %posttrans of grub2-i386-pc-2.06-150500.15.1.noarch

The remaining 182 packages took 6 min. That's not too bad.

Whether kernel-default/grub2-i386-pc were responsible for the slow UI is
something I cant tell. Both tasks are known to consume memory and CPU power,
but this should not persist until reboot. The log at least contains no hint to
a problem the installer had recognized. An by now We did not receive any
similar reports.

The log lets me assume that you are using xfce? If that's right we can move the
bug to the xfce maintainers. Maybe they have some more ideas on how to check
the reason for the slow UI.
