After looking over the feedback from Brian and Austin and reviewing
the actual sizes of the DLEs, I ended up with this sort of thing:
inparallel 15
dumporder "SSSSSTTTTTsssss"
Which resulted in a reduced time over what I have been seeing. Here
are some stats from amstatus for this config. It looks like I could
drop about half of the dumpers and still be fine. Any idea what causes
the dumpers over the first five to be utilized less?

I am going to give things another week or so and then try breaking up
some of the very large DLEs in the config.
