Oh come on :-).  FreeBSD has some optimizations that are being put in
place that really help it on *86 architectures.  After these optimizations
get completed -- then we are going to start adding features.  I am currently
using FreeBSD in embedded applications and in timesharing applications.  We
just in -current have improved process startup of in-memory segments by
6 times (and originally startup was faster than 386BSD.)  The FreeBSD
people are actually very easy to get along with -- and there is not
elitism.  FreeBSD in on incarnation or another is going to be around for
at least a couple of years (I cannot look ahead farther than that.)  We are
actually improving the technology base of *BSD (we cannot concentrate
on features, since our group is fairly small.)  At least two of us are
actually working *almost* full time on it, and major bugs are usually
fixed within a week or faster (once we are informed.)  Patches that users
come up with are *gladly* accepted, we really look at them.  The advantages
of FreeBSD include:
 
	1) Real VM speedups (many argue this who haven't tried it.)
	2) Easy to get along with people (actually friendly.)
	3) Improved paging algorithm (the old pager basically randomly
	   swapped out pages :-)).
	4) More efficient memory use by paging more of the process (Old
	   versions of *BSD left about 5 pages of a process memory (20K)).
	   If you have say, 20 processes -- 400K can be wasted under
	   swapping conditions!!!!
 
	6) Numerous other kernel improvements.
	7) We have no secret kernel source tree (other than development
	   sources on local machines.) You and others can see exactly
	   what we are doing.
	8) I personally elicit public open discussion of future changes
	   and kernel (VM oriented) enhancements.
 
I even accept phone calls anytime and am usually helpful (others on the
team are like that too...
