If you need to measure the maximum network speed in both directions (in a duplex mode), use the –d option on the client:ĭuring the network test using iPerf, you can monitor your network connection throughput chart through the Task Manager. If you need to test your Internet service provider bandwidth, you can use one of the public iPerf servers (iPerf public host list is available here): In this case, you should start the iPerf server with the command: iperf3 -s –u). User the –R option on the client for this.īy default, the utility generates TCP traffic, if you need to check your network bandwidth for UDP packets, you must use the –u option. You can run iPerf in reverse mode (the server sends data, and the client accepts). Reminder : To be able to fully utilize your unifi, please do the speedtest using a LAN cable (CAT5/CAT6) and please make sure your laptop/PC network adapter can support high speed connection, If you are using a mobile phone, please note that not all phone can support dual band wifi spectrum 5ghz capabilities hence the speed you received will be. In the continuous tests, when you have to estimate the performance during several minutes (hours), you can set the period of time to display the intermediate results using the –i option. Using the -f argument, you can change the speed format (bits, kilobits or megabits). 307 MB of data was transferred ( Transfer column) with the symmetric speed (sender=receiver). In this case the average network bandwidth between two hosts is 85.9 Mbit/s. In the final report, we are interested in the values of the Bandwidth column listed in the last line. In my example, the test lasted 30 seconds. -P 8 – is the number of parallel threads (streams) to get the maximum channel load.-t 30 – is the time in seconds for the test to be done (by default, it is 10 seconds).-w 32768 – increase the TCP window size.-c 192.168.1.200 – IP address of the iPerf server.
