Use the zperf shell utility to evaluate network bandwidth.

Description
|
|
***********
|
|
|
|
The zperf sample demonstrates the :ref:`zperf shell utility <zperf>`, which
|
|
allows to evaluate network bandwidth.
|
|
|
|
Features
|
|
*********
|
|
|
|
- Compatible with iPerf_2.0.5. Note that in newer iPerf versions,
|
|
an error message like this is printed and the server reported statistics
|
|
are missing.
|
|

|
|
|
- Client or server mode allowed without need to modify the source code.
|
|
|
|
Supported Boards
|
|
****************
|
|
|
|
zperf is board-agnostic. However, to run the zperf sample application,
|
|
the target platform must provide a network interface supported by Zephyr.
|
|
|
|
This sample application has been tested on the following platforms:
|
|
|
|
- Freedom Board (FRDM K64F)
|
|
- QEMU x86
|
|
- Arm FVP BaseR AEMv8-R
|
|
- ARM BASE RevC AEMv8A Fixed Virtual Platforms
|
|
|
|
For best performance, the sample configures a lot of network packets and buffers.
|
|
Because of this, the sample's RAM requirements are quite large. In case the
|
|
sample does not fit into target platform RAM, reduce the following configs:
|
|
|
|
.. code-block:: cfg
|
|
|
|
CONFIG_NET_PKT_RX_COUNT=40
|
|
CONFIG_NET_PKT_TX_COUNT=40
|
|
CONFIG_NET_BUF_RX_COUNT=160
|
|
CONFIG_NET_BUF_TX_COUNT=160
|
|
|
|
Requirements
|
|
************
|
|
|
|
- iPerf 2.0.5 installed on the host machine
|
|
- Supported board
|
|
|
|
Depending on the network technology chosen, extra steps may be required
|
|
to setup the network environment.
|
|
|
|
Usage
|
|
*****
|
|
|
|
See :ref:`zperf library documentation <zperf>` for more information about
|
|
the library usage.

|
Wi-Fi
|
|
=====
|
|
|
|
The IPv4 Wi-Fi support can be enabled in the sample with
|
|
:ref:`Wi-Fi snippet <snippet-wifi-ipv4>`.
