I see the "-evp" parameter makes the difference in "openssl speed":

> openssl speed -engine cryptodev -elapsed -evp aes-128-cbc aes-128-cbc
engine "cryptodev" set.
You have chosen to measure elapsed time instead of user CPU time.
To get the most accurate results, try to run this
program when this computer is idle.
