This indicates that you have INVARIANTS enabled (and you're probably
running GENERIC, so you also have WITNESS).  These will debugging
features will substantially impact performance.  To do performance
testing on head, you need disable these options from your kernel
config:

nooptions INVARIANTS
nooptions WITNESS
nooptions MALLOC_DEBUG_MAXZONES

Also, set MALLOC_PRODUCTION=yes in /etc/make.conf.  Then rebuild your
world and kernel and try again.
