Stunnel will use session-id caching (session resupmtion) by default if
available.  The client, when connecting, says "Hey, I've got this old
session-id, want to use it?" and if the server is cool with it, it will
skip the normal/computationally intensive handshake.

When you run Stunnel, include the full debugging and look for
'session id reuse' in the output - if you're getting sessions
reused, then everything's working correctly.
