  Once connected, the client will send TCP or UDP traffic as fast as possible to
  the server.
! Both the client and server will periodically display throughput
! statistics along with any kernel variables the user has selected to
  sample (using the
  .Fl k
  option, which is only available in TCP mode).
  A list of available kernel variables may be obtained using the
  .Fl l

  Once connected, the client will send TCP or UDP traffic as fast as possible to
  the server.
! Both the client and server will periodically compute and display throughput
! statistics.
! The server starts computing these for UDP on receipt of the first datagram,
! and stops for TCP when it has no connections.
! This display also includes any kernel variables the user has selected to
  sample (using the
  .Fl k
  option, which is only available in TCP mode).
  A list of available kernel variables may be obtained using the

+ A summary over the periodic throughput statistics is displayed on exit.
+ Its accuracy may be increased by decreasing the
+ .Ar interval .
+ The summary bytes and duration cover the interval from transfer start
+ to process exit.
