I have the following in /boot/loader.conf and it seems to be doing well for me on FreeBSD-i386 with 1G RAM. vm.kmem_size="512M" vm.kmem_size_max="512M" vfs.zfs.prefetch_disable="1" vfs.zfs.arc_max="150M" kern.maxvnodes="400000" Most of these settings came from various mailing list postings. It's possible that some don't do anything useful, but I haven't had a zfs related panic since.
