This option simulates payload in iperf2, which is just repetitive pattern (ASCII '0..9' repeating), as opposed to iperf3 where payload is random. It might help in testing and reveal problems in networking gear with hardware compression (including WiFi access points), where iperf2 and iperf3 perform differently, just based on payload entropy.
