Booting openSUSE Leap 42.1 extremely slow


Hardware is the PC in my signature.

This is what I tried:

Code:
me@PC:~> systemd-analyze critical-chain
The time after the unit is active or started is printed after the "@" character.
The time the unit takes to start is printed after the "+" character.

           330ms systemd-modules-load.service
Then:
Code:
me@PC:~> systemd-analyze
Startup finished in 2.017s (kernel) + 2.296s (initrd) + 21.582s (userspace) = 25.896s

me@PC:~> systemd-analyze plot > boot4.svg
In stark reality it is even slower, about one minute to graphical login and another 30 seconds to the GUI. Lots of disk activity. When I had Mint running prior to booting SUSE time may go up to two and a half minutes.

Darn. How do I attach a file here? I wanted to post the plot but I don't find how to do that...

i find it easier to have "systemd-analyze" output a svg image and SEE what is causing the roadblock

the svg is set up to show the time and sequence of booting

most of the time the network connection is a roadblock
or the ati/nvidia driver

as to the plot
convert the svg to a png ( using Gimp) and use imgur or imgbox
-- the image is BIG, imgbox has a 10 meg file size max


this is a few years old
https://lizards.opensuse.org/2012/07...2-second-boot/

or a post on the suse forum
https://forums.opensuse.org/showthre...-time-openSUSE

i am booting 13.2 at 45 sec. on a 5 year old computer

That's what I did. I wanted to show the plot here, but somehow the "attach file" box doesn't work on LQ?!?

It seems to be the firewall.

Already done (created a .jpg)

Why not post the svg then? <edit> Ah, they're not accepted. Neither imgur nor imgbox work for me (image too large or no reaction on clicking upload ). But why doesn't it work on LQ? </edit>

<edit2> Also I don't really know how to interpret the systemd blame plots </edit2>

Will read the links now, thanks.
