ZFS Encryption method question?

[tangoseal]

What method would you select using the following criteria:

1. Which one will yield fastest performance on current Intel processors?
2. Which one will yield the highest level of security?

AES-XTS
AES-CBC

The 3 below are obviously not hardware accelerated but how do you think they would perform? I know I can use a 448bit key with Blowfish in ZFS.
