iperf3一款主动式网络性能测量工具，主要用途是测量IP网络上可达的最大带宽。它能模拟并测量TCP、UDP和SCTP等主流协议的吞吐量、丢包率、抖动和重传等关键网络性能指标，由于原版iperf3是个命令行程序，并且是全英文状态，不适合普通人测试使用，所以通过deepseek使用powershell写了个简单GUI界面，方便普通人测试自己主机网络情况，由于代码是全有deepseek编写，欢迎大家反馈问题

复制代码

使用方法，保存代码为ps1，右键使用powershell运行，此时无法正常以管理员权限运行，无法更改ip地址，如果需要管理员运行，可以下载附件文件放入iperf3的相同目录下运行

目前测试功能是正常的，但是客户端模式下，同时双向测试右侧信息显示有问题，会一直重复刷新
