Reading through this, I get the impression it's 3 new connections (key
negotiations) per second (instead of, for instance, 100 for
unencrypted traffic).  The cost of the symmetric encryption isn't
mentioned in the article, but I assume it's not the bottleneck.

(The article isn't very explicit.  I could be wrong in my
understanding of it.)

This is bad news for SMTP, since its traffic is made up of short-lived
sessions, but there might be ways to lessen the impact (multi-session
keys, for instance).
