Alexander, try running the installation with this boot option:
inst.updates=https://kparal.fedorapeople.org/tmp/no-spinner.img
It should disable spinner animation. Then compare the CPU usage. I
still haven't gotten to reporting it as a bug, but it's true that
the spinner seems to be a *gigantic* performance hog, making all our
installations take much longer, especially in VMs.
Now I come to notice it, GTKSpinners don't seem to spin at all in TC7
and TC8. They do spin on my desktop. Not sure if there's a package
difference or it's a KVM vs. real hardware thing, but they're broken
with at least both 'vga' and 'qxl' in a KVM. Just burning a USB stick
to see if it's the same on bare metal. Probably GTK+ 3.15.9 is
involved.
