I want to measure performance of my server. The architecture is Apache2 talking to Tomcat over mod_jk. Requests are over HTTPS with mutual authentication. The client does not reuse connections, therefore I believe a new SSL session is established for each transaction.
If I configure Apache to log
%D in mod_log_config, does that duration include the time spent doing SSL, including the TLS handshake? If not, how do I measure that part of the transaction?
