	I'd be willing to bet that it has to do with threading.  FreeBSD 
doesn't support POSIX threads very well, or even any other kind of 
threads.

	BIND-9 compiled with SMP support and POSIX threads runs a lot 
faster on Linux than on FreeBSD, and the reason is known to be 
FreeBSD's current poor support for threading.  Believe me, Paul Vixie 
is very keen to get this issue resolved.  ;)
