I have a lot of experience running 'openssl speed' tests and these 
numbers would not worry me too much - if you were to run each of these 
tests 10 times **on an empty system** , then average the results , then 
most likely you will find that the results are within 5% of each other.

IOW, OpenSSL 1.1.1 is just as fast/slow on this purely artificial speed 
test as 1.1.0

HTH,
