It is slower for small buffer (<256 octets), because the overhead of
the driver. But it should be better for 1024 and a lot of better for
8192.

Did you try with -evp in openssl?

The best is to crypt a file to test :
 dd if=/dev/zero bs=4k count=100000 | openssl enc -aes-128-cbc -e
 -out /dev/null -nosalt -k abcdefhij -engine cryptodev

There was a problem on FreeBSD 6 and 7, openssl did not use the
cryptodev engine by default and you have to patch openssl if you want
to use the engine with ssh (for example).
