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

Ok granted this is a server sat in my house and it is not a "mission"
critical server in a large business, personally I have can live with ZFS
taking a bit longer vs resilience. From just looking at my system at the
moment I have 1.8GB of free ram from a total of 4GB.
