As far as I understand it, FreeBSD does not have a separate disk buffer cache, it uses the regular VM system and therefore the effective amount of memory devoted to disk buffers is dynamically tuned at runtime based on VM load and allocation demands. See http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/vm.html#INTERNALS-VM for more.
