I'm testing all 4 possibilities. The 30% slow down is from clear text
direct to jetty verses clear text proxied to jetty.  No ssl. That makes
sense to me as the proxy requires handling by 2 processes with the same cpu
available.

The 100% improvement is comparing direct ssl with proxied+offloaded ssl. It
shows the ssl performance gains are more than enough to compensate for the
costs of proxying.
