If you do man tunefs it you will see how it warns
that less than 15% is dangerous. (even though normally
only 8% is reserved. It's especially dangerous when
you have Many Many files. (and a large hard drive -
thus more to manage)

For shame. A "your question is too dumb to have
written to our mailing list"? I hope you are not
trying to represent the great open arms of FreeBSD and
the questions mailing list. My Question is quite
appropriate for either list. Nor should someone even
be given the feeling their questions are too basic to
bother us with! (unless your aim is to drive people
away)
However, I was hoping someone could point me more
towards a white paper or some such other information.
Such as that used by the man page for tunefs, that
recommends not using more than 15% or drive capcity
and how performance can degrade 3 fold of the
performance at 10%. So that I can work up my own
percentages for my type of file usage. (and yes Inode
usage is fine)
