Note: Signiant transfers will read the packet loss and, within the 1-3% range, throttle the transfer speed in order to provide the best transfer. iperf running on pfSense® software is NOT a suitable way of testing firewall throughput, as there is a significant difference between performance of traffic initiated or terminated on the firewall and traffic traversing the firewall. .

To test your connection to one of the computers on your own network, you need to run Iperf as a server. Another change is that iperf3 is single threaded while iperf2 is multi-threaded.
