Would this have any effect on the speed of an 'ls' in the .zfs/snapshot/
directory? I'm guessing not, since that would have more to do with generic
directory listings and general slowness in 'ls'. But one can dream. :)
Afterall, the 'ls' *is* just querying the name and not all of the other ZFS
We do most of our snapshot accesses and listing via the .zfs/snapshot/
directory, which can take several seconds before the list starts to appear
when there's a couple of hundred snapshots there.
