I just ordered a 2.2GHz MBP 15" which apparently supports the AES-NI instruction sets. According to Anandtech, SL doesn't uses this feature for acceleration disk encryption. Does anyone know if Lion supports this in FileVault 2?
(and yeah I did google it and found similiar threads but no one knows the answer)
 
Performance

In AES-NI Performance Analyzed, Patrick Schmid and Achim Roos found, "... impressive results from a handful of applications already optimized to take advantage of Intel's AES-NI capability".[10] A performance analysis using the Crypto++ security library showed an increase in throughput from approximately 28.0 cycles per byte to 3.5 cycles per byte with AES/GCM versus a Pentium 4 with no acceleration.[11] [12]

Software supporting AES instruction set

The following software supports the using of AES instruction set.

7-Zip 9.20
Bitlocker
Citrix XenClient 1.0 and on
Cryptographic Development Kit (CDK) 7.0 from Information Security Corp.[13]
Cryptography API: Next Generation (CNG) (requires Windows 7) [14]
Crypto++ 5.6.1
CyaSSL - an open source SSL/TLS implementation supporting AES
DiskCryptor 0.9
DiskSec 1.85
dm-crypt

The Bat! 4.3
TrueCrypt 7.0
VMware Workstation 7.1
WinRAR 4.01
 
That's awesome news. I was worried that performance would take a hit after turning on FileVault (Anandtech benchmark proved so under SL), but now I think it's safe to say that FileVault 2 on AES-NI equipped Macs is without any performance decrease.
