FreeBSD filesystem performance in Enterprise

Not trying to start a holy war -  just  looking into hard facts to 
support some systems I'm designing.   FFS will either work, or it 
won't.  Black or white.

The type of I/O I'm talking about will be in the 100's of thousands of 
email messages (probably more) per day... obviously the underlying OS, 
filesystem tuning, hardware are also an issue.  I'm simply trying to 
gain some insight into other's experience with FFS, etc.


Thanks.
