Openwrt安装iperf3工具测试网络吞吐量带宽

部署完软路由系统后，有个很重要的动作就是测试并调试网络带宽性能。在路由器行业比较常见的网络吞吐量性能测试工具有图形化测试工具IQ ixChariot，以及命令行测试工具iperf。这里在Openwrt端我们以Iperf3为例来展示如何测试网络性能带宽。

一、Openwrt服务器端部署Iperf3工具

进入openwrt后台

#ssh root@192.168.1.10

#cd tmp

下载openwrt软件包

#wget http://downloads.openwrt.org/releases/19.07-SNAPSHOT/packages/x86_64/base/iperf3_3.7-1_x86_64.ipk

安装iperf3

#opkg install iperf3_3.7-1_x86_64.ipk

二、客户端部署iperf3工具

这里以Mac OS客户端为例，其他Linux客户端和Windows客户端请自行在网上搜索之。

安装Homebrew 包管理器

#/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

安装iperf3

#brew install iperf3

三、启动测试流程

1.服务器端启动iperf进程

# iperf3 -s  //临时开启进行，可以实时显示吞吐量

# iperf3 -s -D //开启后台常驻进程

2. 客户端开启测试

#iperf3 -c 192.168.1.10  //单线程TCP测试，这里的IP地址填你的openwrt路由器

#iperf3 -c 192.168.1.10  -b 1000m -t 300 -i 1 -u -P 2 #多线程UDP测速

四、观看测试结果

1. 服务器端开启iperf3 -s 后，可以实时监听测试结果，如下图

同时在Openwrt的系统实时监测图形化界面也可以看到测试结果

2. 客户端测试完成后，会显示测试结果

#iperf3 -c 192.168.1.10 -t 30  //测试30s
