Right away when looking at the first result, which is the SQLite database test, enabling Intel AES-NI support makes a huge difference. AES-NI for the eCryptfs solution did not affect the performance, but with the fully encrypted file-system using dmcrypt, the improvement was huge for this Intel Sandy Bridge notebook with an Intel X-25 SSD.

The CPU usage was also slightly lower with the encryption using the AES-NI instruction set efficiently.
