You should find a message written by Oliver Fromme at 26-th of April 2007,
subject "Re: UFS: optimization changed". That's an answer to your question... :)
(here's the link http://docs.freebsd.org/mail/archive/freebsd-stable.html)

> newfs(8) manpage reports:
> However, tunefs(8) manpage reports:
>      -m minfree
>              Specify the percentage of space held back from normal 
> users; the minimum free space threshold.  The default value used is 8%. 
> Note that lowering the threshold can adversely affect performance:
> 
> o   Settings of 5% and less force space optimization to always be used 
> which will greatly increase the overhead for file writes.

> Or, am I just reading it wrong?
