WebIn iperf3 the column Retr stands for Retransmitted TCP packets and indicates the number of TCP packets that had to be sent again (=retransmitted). The lower the value in Retr the better. An optimal value would be 0, meaning that no matter how many TCP packets have been sent, not a single one had to be resent. Web22 mrt. 2024 · For iperf 2.0.13 use iperf -c -b 1pps.
