Well, as you predicted, adding the fifth Collection back to the G5 (it had been there all along, but moving the dongle back activated it) increased the initial start-up time to 2:10. I guess that means each Colleciton takes additional time. It seems unlikely that adding five more would increase the load time to seven minutes, but it's possible.
Another issue is that the Collection I "moved" back didn't appear in the Vienna Instruments player even though I ran the directory utility, but I'm not going to worry about that right now.
