+# IPerf 使用说明
+
+IPerf 可用于网络带宽测试，可在 Windows、Linux、Android、MacOS 和 iOS 系统下运行。主要有 IPerf2 和 IPerf3 两大版本。
+
+IPerf 可做为 Server 端或 Client 端运行，Client 发起与 Server 端的通讯，并对通讯性能进行分析。
+
+## 单线程 TCP 测试
+
+```sh
+# Server
+iperf3 -s -p <port>
+# Client
+iperf3 -c <server ip> -p <server port> -i <interval> -t <time>
+```
+
+## 多线程 TCP 测试
+
+```sh
+# Server
+iperf3 -s -p <port>
+# Client
+iperf3 -c <server ip> -p <server port> -i <interval> -t <time> -P <parallel>
+```
+
+## 单线程 UDP 测试
+
+```sh
+# Server
+iperf3 -s -p <port>
+# Client
+iperf3 -u -c <host> -p <port> -i <interval> -t <time>
+```
+
+## 多线程 UDP 测试
+
+```sh
+# Server
+iperf3 -s -p <port>
+# Client
+iperf3 -u -c <host> -p <port> -i <interval> -t <time> -P <parallel>
+```

+| -P #        | Client specific: number of parallel client streams to run          |
+| -t #        | Client specific: time in seconds to transmit for (default 10 secs) |
+| -u          | Client specific: use UDP rather than TCP                           |
