while it CAN be set up on 256MB machine with a little big flags in 
loader.conf (should be autotuned anyway) - it generally takes as much 
memory as it's available, and LOTS of CPU power.

with similar operations ZFS takes 10-20 TIMES more CPU than UFS and it's 
NOT faster than properly configured UFS. doesn't  make  any sense
