The one other thing I hadn't answered before, each directory has on
average 1,293 files, deviation of less then 100 each direction. In the
old structure some directories had over 50,000 files and it didn't seem
to slow it down. Dir_index was not enabled on the systems, so I enabled
it on one node, waiting for something to finish before I can unmount it
and run e2fsck -fD on it.
