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.
