If I want swap I use a zvol on the pool - if you set the zfs porperty 'org.freebsd:swap' to 'on' then it will swaap to it quite happily. But in actual practice I usually stuff the machine with RAM and run without swap enabled. In the case of the specific machine in question it just does simple low volume file serving and has 44GB in it, which is plenty for a ZFS fileserver. -pete.
