I've found the openssl speed tests to be an unreliable measure of comparison.  I think you might be better served by comparing the
performance of encrypting/decrypting content, such as
dd if=/dev/zero bs=1M count=100 | openssl aes-128-cbc -e -pass pass:secretpwd | \
 openssl aes-128-cbc -d -pass pass:secretpwd >> /dev/null

And for a baseline use
dd if=/dev/zero bs=1M count=100 >> /dev/null 

Kind regards, Dewayne
