I've just started playing with this and finding the same behaviour. I
started with a full scan on all cores on my 120K+ database and left it
for a few days. This reported about 40% complete. So I started looking
at the other options and I'm finding the same as you. If anything
progress seems slower when in Non-Assigned and Update mode but it of
course difficult to be objective.
