What's the expected performance overhead for secured vs. unsecured site 2 site protocol in NiFi?

I don't have any real numbers to share though I found this article on the topic interesting https://www.maxcdn.com/blog/ssl-performance-myth/ and found that it aligns to what I've observed as well.

There are relatively few cases where unsecured site-to-site is appropriate in comparison to secured site-to-site.
