Did you by any chance build your own kernel? If so did you leave things
like this in:

options         INVARIANTS              #Enable calls of extra sanity
options         INVARIANT_SUPPORT       #Extra sanity checks of internal
options         WITNESS                 #Enable checks to detect deadlocks
options         WITNESS_SKIPSPIN        #Don't run witness on spinlocks

These will significantly slow down a FreeBSD machine. They're there mainly
for debugging purposes, but if you want speed you should take them out.
