ZFS on top of GELI / Intel Atom 330 system

[Dan Naumov]

Now that I have evaluated the numbers and my needs a bit, I am really
confused about what appropriate course of action for me would be.

1) Use ZFS without GELI and hope that zfs-crypto get implemented in
Solaris and ported to FreeBSD "soon" and that when it does, it won't
come with such a dramatic performance decrease as GELI/ZFS seems to
result in.
2) Go ahead with the original plan of using GELI/ZFS and grind my
teeth at the 24 MB/s read speed off a single disk.


>> So basically on this system:
>>
>> unencrypted ZFS read: ~70 MB/s per disk
>>
>> 128bit Blowfish GELI/ZFS write: 35 MB/s per disk
>> 128bit Blowfish GELI/ZFS read: 24 MB/s per disk

Our difference is that my hardware is already ordered and Intel Atom
330 + D945GCLF2 + 2GB ram is what it's going to have :)
