H A DSSL_get_handshake_rtt.pod6 - get round trip time for SSL Handshake
16 SSL_get_handshake_rtt() retrieves the round-trip time (RTT) for I<ssl>.
36 In addition to network propagation delay and network stack overhead, this
37 metric includes processing time on both endpoints, as this is based on TLS
38 protocol-level messages and the TLS protocol is not designed to measure
39 network timings. In some cases the processing time can be significant,
46 Returns -1 if, while retrieving the TLS handshake RTT, an error occurs.
