A 50G filesysten created with defaults has more than 6 million inodes
and on a system without a decent amount of memory checks pretty quick.
If you run ffs2 with softdep, and optimization kicks in that will make
the number of *used* inodes the driving factor, instead of the total
number of inodes on a fs.

Likely all will be unclean and need to be checked.
Anyway make sure the max number of files per directory doe not grow
without bound. Use a max of a couple of 10000 files per directory as a
rule of thumb.
