Iperf Example

This example implements the protocol used by the common performance measurement tool iPerf. Performance can be measured between two ESP32s running this example, or between a single ESP32 and a computer running the iPerf tool

Demo steps to test station TCP Tx performance:

Build the iperf example with sdkconfig.defaults, which contains performance test specific configurations
Run the demo as station mode and join the target AP sta ssid password
Run iperf as server on AP side iperf -s -i 3
Run iperf as client on ESP32 side iperf -c 192.168.10.42 -i 3 -t 60

The console output, which is printed by station TCP RX throughput test, looks like:

esp32> sta aptest

I (5325) iperf: sta connecting to 'aptest'

esp32> I (6017) event: ip: 192.168.10.248, mask: 255.255.255.0, gw: 192.168.10.1

esp32> iperf -s -i 3 -t 1000

I (14958) iperf: mode=tcp-server sip=192.168.10.248:5001, dip=0.0.0.0:5001, interval=3, time=1000

Steps to test station/soft-AP TCP/UDP RX/TX throughput are similar as test steps in station TCP TX.
