Do not know how to use linux iperf commands for network performance testing? In fact, it is not difficult to solve this problem. Let the editor take you to learn how to solve it. I hope you will gain a lot after reading this article.

The iperf command can be used to test the performance of some network devices such as routers, firewalls, switches, etc.

Syntax format: iperf [parameters]

Common parameters:

-l sets the length of the read-write buffer-p sets the port, which is consistent with the listening port on the server side-o redirects the output to the specified file-t sets the total time to transfer-v displays version information and compilation information and exits

Reference example

At the same time, the client initiates 30 connection threads to the server, using 5Mbps as the data transmission rate:

[root@linuxcool] # iperf-u-c 192.168.1.1-b 100m-d-t 60

In tcp mode, the client uploads the bandwidth test to the server 192.168.1.1, and the test time is 60 seconds:

[root@linuxcool] # iperf-c 192.168.1.1-P 30-t 60

Start Iperf into server mode:

[root@linuxcool] # iperf-s

Test with the default settings of the server and the client:

[root@linuxcool] # iperf-s-w 300K

Test two-way transmission:

[root@linuxcool] # iperf-c 59.128.103.56-f K-I 2-w 300K-u Thank you for reading this article carefully. I hope it is helpful for the editor to share the content of network performance test using linux iperf command. At the same time, I also hope you can support us, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you!
