Fair enough. I wouldn't expect commodity AES hardware to be able to
encrypt at 10Gb line speed. It will saturate 1Gb, but yes, 10Gb the AES
is probably going to be a bottleneck (and IS a bottleneck in your
configuration).
I was assuming OP was on 1Gb and not 10Gb. The mentioned RPi3 which, last
I checked, is only 1Gb.
