I've read a lot about how fast TrueCrypt 7.0 is with it's support for AES hardware acceleration and multi-core/multi-thread support. Will dmcrypt/LUKS offer the same performance enhancing features on a full disk encryption setup on Ubuntu 11.10?

dmcrypt/LUKS does benefit from Intel AES hardware acceleration.

See this article for some benchmarks showing the advantages of AES-NI hardware acceleration.

What about multiple CPU cores? – ʇsәɹoɈ Feb 11 '15 at 2:55

The answer is NO. There is only 1 core being used. So a fancy 8 core or 4 core system won't be showing its full potential. And this post is 3 years old. And still no improvement on that.
