LOL! Its always a trade off.

In the limiting case a couple of dozen hubs and set up all 40 to run in
parallel, the go out, have dinner, see a movie, spend the evening with
your significant other, and come back the next day.

It beats hanging around doing the swap-restart cycle over and over.

You have to figure out not just elapsed/clock time but the time you
spend doing and waiting.

Personally I prefer going off and doing something else, even if its only
reading a book or cooking a meal, and letting the 'incredibly slow'
stuff grind through, to sitting at the terminal waiting, waiting, and
doing the swap-restart step and repeat one by one, even if that does
each unit faster.

And it may be that the elapsed time for 4 in parallel, or 7, 8, 10 in
parallel is the same as the elapsed time one at a time, but doing the
setup all at once saves you time.
