    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]

    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.
