OPENWRT使用iperf3测试内网带宽的方法
OPENWRT使用iperf3测试内网带宽的方法，首先OPENWRT需要安装netspeedtest组件
netspeedtest组件依赖iperf3组件,直接在OPENWRT-软件包-搜索“netspeedtest”安装即可
所以，客户端也需要安装iperf3
比如Mac系统下安装iperf3
brew install iperf3
在客户端使用以下命令测试内网带宽，
iperf3 -c 10.0.0.1
返回如下数据，

建议多测试几次，因为使用的是软路由，某无线路由器做为AP,感觉数据不理想
尤其是第一次测试时，带宽数据非常差，下面是第一次测试的数据
