Hi, ZFS is recommended for most cases, but it gets very slow when you
need synchronous writes (ZFS/NFS: 5 mbits against ISCSI/UFS: 80mbits on
I got terrible performance on vmware using a freebsd zfs as datastore.
If your raid hardware has a battery (to flush the cache in case of power
down) you will got a much better performance on this case
You can improve performance using a SSD as cache (ZIL cache? Im not a
guru on this stuff, you should google it, hehe)
