# Iperf Example
|
|
|
|
## Note about iperf version
|
|
The iperf example doesn't support all features in standard iperf. It's compitable with iperf version 2.x.
|
|
|
|
## Note about 80MHz flash frequency
|
|
The iperf can get better throughput if the SPI flash frequency is set to 80MHz, but the system may crash in 80MHz mode for ESP-WROVER-KIT.
|
|
Removing R140~R145 from the board can fix this issue. Currently the default SPI frequency is set to 40MHz, if you want to change the SPI flash
|
|
frequency to 80MHz, please make sure R140~R145 are removed from ESP-WROVER-KIT or use ESP32 DevKitC.

## Introduction
|
|
This example implements the protocol used by the common performance measurement tool [iPerf](https://iperf.fr/).
|
|
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:
|
|
|
|
1. Build the iperf example with sdkconfig.defaults, which contains performance test specific configurations
|
|
|
|
2. Run the demo as station mode and join the target AP
|
|
sta ssid password
|
|
|
|
3. Run iperf as server on AP side
|
|
iperf -s -i 3
|
|
|
|
4. 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:
|
|

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