Description andreas 2016-08-04 19:20:28 UTC
movie with ksplash of my virtualbox 
https://dl.dropboxusercontent.com/u/1642456/VDG/ksplash/ksplas-with-cut-plymouth.avi
8 sec plymouth (linux boot time)
11 sec ksplash
4 sec desktop is finished
=====================
23 sec (1/3 for linux 2/3 for plasma)

movie without ksplash
https://dl.dropboxusercontent.com/u/1642456/VDG/ksplash/ksplas-without-cut-plymouth.avi
8 sec plymouth (linux boot time)
11 sec desktop is finished
=====================
19 sec (42% for linux 58% for plasma)

Reproducible: Always


Actual Results:  
18% faster start and the flickering is also there when you activate plymouth.
Comment 1 andreas 2016-08-04 19:28:51 UTC
when you look only to plasma (cause the linux kernel start 8 sec is fast enough) you can 

reduce starting to for 25% only when turn off ksplash

as the desktop is available immediately it FEEL even faster

my pc isn't that fast, but I have a ssd
Comment 3 andreas 2016-08-06 05:34:54 UTC
in win7 you lock in than there is a very short black frame (depand on your machine if you will see it) and than you have the desktop with the panel, but you see that the elements from the system tray will start.

in os-x you see also some flickering when the desktop was build.

in my mind it would be more usefull to turn off ksplash animation by default. the start would be faster and cause the desktop is immediat visible it feels MUCH more faster and the user wouldn't say PLASMA is a heavy desktop environment.

Does this still happen to you with Plasma 5.21? Also, how about when using the new systemd startup? See http://blog.davidedmundson.co.uk/blog/plasma-and-the-systemd-startup/ I ask because there have been a lot of improvements here recently.
