profiling startup

I see there was some discussion over startup times on IRC.

If you want to profile startup you'll want to use systemd-bootchart
[1] it tracks resources usage during boot, which is valuable
information in finding out why it may be slow (outside slowness in

For debugging the actual session-start you can have a look at [2]
which will tell you how to profile a plasma session on x or wayland.

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.
