I added the indices back and performance dramatically increased. I
assume my tables needed a repair and that that was the initial problem
(maybe caused by the upgrade I had recently done from 2.2.8 to 5.0.3).
While restores essentially hung before I dropped the indices and
dropped to maybe 30 seconds to build a ~15GB directory tree, after
adding them back, it's now nearly instantaneous.
