In bidirectional mode, the measured throughput in bidirectional mode is less
than the ideal in one way mode. This is due to the overhead caused by
interleaving returning ACK frames into the transfer. The ideal throughput of the
instrument in bidirectional mode is calculated by considering the estimated
interleaving returning ACK frame.
In case of connecting iPerf server, the "Interval" result of iPerf server is
displayed more 1 second than the "Actual Transfer Time" result of the
instrument. When you check the result of iPerf server, it is recommended to set
the duration of the test by sufficient long period.
