Appears to be a memory hog, needs about 1 > GB especially if large file transfers may occur over gigabit ethernet 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
