Then I have run newfs on that GELI device and mounted it as a volume. It's less than an ideal way of having encryption on ZFS (you get some of the benefits of ZFS, but the filesystem on top of GELI is still UFS), but it works anyway. On my 2.13Ghz Core2 Duo with 2GB of RAM under amd64-current, my system load doesn't break much of a sweat, reading to and from the GELI volume - and speeds are tolerable. Since I have the Promise card issue, I can only give bechmarks dated from the 200706 snapshot, and I'm sure zfs performance has improved since then.Received on Tue Aug 28 2007 - 00:10:56 UTC
