There really isn't a 'buffer cache' in FreeBSD. About 5 years ago FreeBSD was changed so that buffers weren't used to cache filesystem data - instead they are used as a mechanism to map cached pages from the VM system into the kernel address space. All file caching now occurs in the VM system and is completely dynamic in size, and varies with other activity in the system. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com Pave the road of life with opportunities.
