详细使用方法：
iPerf is a command-line tool used to measure the performance of a network. Here are some examples of how to use iPerf:
Testing the bandwidth between two hosts:
On the server host, run the following command to start iPerf in server mode:
Copy code
iperf -s
On the client host, run the following command to start iPerf in client mode and connect to the server:
php
Copy code
iperf -c <server-hostname-or-IP>
The client will now perform a bandwidth test and report the results to the console.
Testing the bandwidth in both directions (bidirectional test):
On the first host, run the following command to start iPerf in server mode:
Copy code
iperf -s
On the second host, run the following command to start iPerf in client mode and connect to the first host:
php
Copy code
iperf -c <first-host-name-or-IP> -d
The client will now perform a bidirectional bandwidth test, measuring the bandwidth in both directions and reporting the results to the console.
Testing with a specified duration:
On the server host, run the following command to start iPerf in server mode:
Copy code
iperf -s
On the client host, run the following command to start iPerf in
