- Description from man page
The s_time command implements a generic SSL/TLS client which connects
to a remote host using SSL/TLS. It can request a page from the server
and includes the time to transfer the payload data in its timing measurements.
It measures the number of connections within a given timeframe,
the amount of data transferred (if any),
and calculates the average time spent for one connection.
