I've heard that disk encryption works reasonably faster when CPU supports AES-NI. How can I check if my CPU supports it? Does the Ubuntus default encryption (dm-crypt
) use it by default or do I have to enable it?

grep aes /proc/cpuinfo
if there is output that starts with flags
and there is something like aes
your system supports it.
You can also check this list from intel (268 boards support it).
