1.下载方式
1.1 centos服务端
#直接下载 yum -y install iperf3 #在有网的机器下载离线安装包（将包上传到其他服务器即可） yum -y install iperf3 --downloadonly --downloaddir ./
1.2 win10客户端（下载之后正常安装exe即可）
https://iperf.fr/download/windows/iperf-3.1.3-win64.zip
2.使用
2.1 服务端使用
iperf3 -s #默认监听5201端口，可以修改
2.2 客户端使用
iperf3 -c 172.16.16.19 -n 1g #-n 指定传输数据包大小
2.3 结果展示

2.4 总结
可以看出从客户端到服务端的带宽发送和接受是760Mbits/sec，也就是大概千兆的带宽
