You have probably hit the nail on the head.  The OSKit's malloc is
pretty slow.  You might try using the FreeBSD C library (I think,
someone from Utah should correct me if I'm wrong...).  Also, you can
build the OSKit with --enable-profiling to get a gprof dump of where
the time is being spent.  Look at CH 29 (egad!) of the manual.
