Here's the patch helped me in the similar situation:
http://lists.freebsd.org/pipermail/freebsd-stable/2007-November/038449.html

If it also does not help, I think LOCK_PROFILING(9) and pmc stats
( http://freebsd.rambler.ru/bsdmail/freebsd-current_2006/msg01581.html ) would 
be useful to see what exactly is slow.

With best regards,
