I have tried to do a quick non-scientific measurement of the length of the installation
(F22 Alpha TC8 Server DVD, all defaults). The times were measured from hitting the Begin
Installation button to the Installation finished message (I configured the root password
during the run). I made two runs for each case, and I worked during the installations in
other applications (mostly web browser), so it might have skewed the results quite a bit.
I can devote some time to do proper testing, if it would increase the chance to have this
fixed soon(er) ;-)
This is with spinner on, during installation phase:

With spinner on, it took me this long:
16m 57s
15m 6s
This is with spinner off, during installation phase:

With spinner off, it took me this long:
4m 59s
5m 9s
The most time difference seems to be in the post-installation phase, where multithreaded
jobs are run and the spinner consumes a lot of available processing power. The
installation phase (rpm installations) seems to be similarly long for both cases, and most
of the time difference is created in the post-installation phase.
