A mere 32% increase in an encryption application?

Are you sure it wasn't the 32-bit version running in a 64-bit OS?

For comparison's sake:

"So comparing the AES numbers, AMD64 is almost twice as fast as x86 in the majority of the tests."

Edit: Here's another encryption reference:

http://www.rsasecurity.com/press_release.asp?doc_id=2926

"For example, RSA BSAFE Crypto-C 6.1 encryption and decryption operations demonstrate a performance improvement of 1.5 to 3 times more than the number of operations per second achieved with RSA BSAFE Crypto-C 6.0.3 software (32-bit)."

Are these Xeons? I may be able to get my hands on one.

The rumor from c't said it sucks. For your data point to mean anything, you need to know how much the Opteron would improve on gpg going from 32b to 64b. Do you?
