Right, but find does not know/care what the filesystem type is --
using the regular user-mode file i/o interface isn't going to give you
access to the B-trees.  You could perhaps write an extention to find
which uses this API, but it would be MacOS specific. (or rather,
filesystem specific)

It's not that the tools are slow, it's that find does not use any sort
of API which allows for direct access to the filesystem information.

ttyl,
