iPerf3测试局域网两台机器的之间的最大带宽

测试局域网两台机器的之间的最大带宽

1. 介绍

工具使用的是iPerf3，官网地址是https://iperf.fr/

Ubuntu，Mac，Windows都可以支持使用，需要在测试的两台机器上都安装上该软件。

iPerf3也是C/S(客户端/服务器端)架构模式，在使用iperf3测试时，要同时在server端与client端都各执行一个程序，让它们互相传送报文进行测试。

2. 安装iPerf3

可以选择使用docker安装，或者根据系统来安装

2.1 Ubuntu安装

执行命令sudo apt-get install iperf3

2.2 MacOS X安装

访问页面https://iperf.fr/iperf-download.php，选择

中的iPerf 3.1.3，点击链接下载为iperf-3.1.3-macos-x86_64.zip，解压之后就是一个脚本文件

3. 带宽测试

我们把另外一台服务器作为服务端，本地机器作为客户端

3.1 远程服务器作为服务端

远程服务器IP是192.168.3.151，通过步骤2安装好之后，执行命令启动server端程序如下，开始监听

➜  ~ iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------

3.2 本地服务器作为客户端

当远程服务器开始监听之后，本地服务器执行命令开始测试，远程机器和本地机器都会有日志打印出来

本地机器日志

那么，简单地说，你可以认为带宽就是14.8Mbits/sec
