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 [email protected] #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

Client and server send and receive data. -w, --window #[KMG] set window size / socket buffer size -C, --congestion set TCP congestion control algorithm (Linux and FreeBSD only) -M, --set-mss # set TCP/SCTP maximum segment size (MTU - 40 bytes) -N, --no-delay set TCP/SCTP no delay, disabling Nagle's Algorithm -4, --version4 only use IPv4 -6, --version6 only use IPv6 -S, --tos N set the IP type of service, 0-255. The usual prefixes for octal and hex can be used, i.e. 52, 064 and 0x34 all specify the same value. --dscp N or --dscp val set the IP dscp value, either 0-63 or symbolic. Numeric values can be specified in decimal, octal and hex (see --tos above). -L, --flowlabel N set the IPv6 flow label (only supported on Linux) -Z, --zerocopy use a 'zero copy' method of sending data -O, --omit N omit the first n seconds -T, --title str prefix every output line with this string --extra-data str data string to include in client and server JSON --get-server-output get results from server --udp-counters-64bit use 64-bit counters in UDP test packets --repeating-payload use repeating pattern in payload, instead of randomized payload (like in iperf2) [KMG] indicates options that support a K/M/G suffix for kilo-, mega-, or giga-
