iperf 程序是一个网络性能测试工具，通常可以用于测试网络设备之间网络速度，支持UDP/TCP与IPv4/IPv6，在Ubuntu2204中安装iperf

下面以A机器（192.168.1.1）到B机器（192.168.1.2）为例，在A/B机器上安装iperf

sudo apt install -y iperf

在A机器上开启iperf服务端

iperf -s -p 55201

常用参数

-s 以服务端运行
-p 监听端口
-V 兼容IPv6

在B机器上连接A机器测试速度

iperf -c 192.168.1.1 -t 30 -p 55201

常用参数

-c 以客户端运行
-p 服务端接收的端口
-t 测试时间
-V 兼容IPv6模式

测试结果输出如下
