profiling startup

[Darin Miller]

Thanks Harold!

I forgot about the boot profiler.  I created 2 profiles and uploaded to an
existing bug:

https://bugs.kde.org/show_bug.cgi?id=392556

Looks like ksplash interacts with plasmashell causing high process usage
for 8 or more seconds longer than plasmashell requires without splash.

But the resulting "boot to desktop" is actually 30s longer with splash.
