iperf3工具
1、简介
iperf3是一款网络性能测试工具，用于测量网络带宽、延迟和数据包丢失率等指标。它支持TCP和UDP协议，可以在客户端和服务器之间进行测试。以下是一些常用的iperf3命令：
- 在服务器上启动iperf3服务：iperf3 -s
- 在客户端上连接服务器进行测试：iperf3 -c <server_ip>
- 测试UDP带宽：iperf3 -u -b <bandwidth> -c <server_ip>
- 测试指定时间内的带宽：iperf3 -t <time> -c <server_ip>
- 测试指定带宽的最大传输单元（MTU）：iperf3 -M <MTU> -c <server_ip>
- 测试多个并发连接：iperf3 -P <num_connections> -c <server_ip>
- 输出测试结果到文件：iperf3 -c <server_ip> -i <interval> -t <time> -J > <output_file>
更多详细的命令和参数可以通过iperf3 --help命令查看。
2、安装
官网：https://iperf.fr/ windows直接解压使用：iPerf 3.1.3 (8 jun 2016 - 1.3 MiB for Windows Vista 64bits to Windows 10 64bits) linux先安装libperf即可：iPerf 3.1.3 - DEB package (8 jun 2016 - 8.6 KiB) + libiperf0 3.1.3 - DEB package (53.9 KiB)
3、使用
在一台电脑作为服务端使用：
D:\Users\User\Desktop\iperf-3.1.3-win64>iperf3.exe -s

-t, --time n 定义本次发送报文测试要持续的时间，单位为秒iPerf通常工作的模式是：持续-t定义的时间（秒）不停的重复发送一组长度为-l定义的数据包。默认值是10秒。
