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.
