iperf2 / iperf3
On iperf 1.7x and 2.0.x, you need to look at the server side output as it is generated there. With iperf3, you can "pull" the server side results with command-line parameter --get-server-output. Suggestion for iperf2.0.x: run iperf -s -u -i 1 on the server side to get 1sec reporting intervals. The iperf is a tool used for testing the network performance between two systems. The iperf application provides more metrics for a networks’ performance. The iperf application is not installed by default, but it is provided by most distributions’ package manager. For CentOS/RHEL/Fedora Systems use the yum, to install the iperf package. iperf3 chart. Requires Bash >= 4, Gnuplot >= 5, iperf3 & jq.

It is significant as a cross-platform tool that can produce standardized performance measurements for any network. Iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions.

Performs a TCP upload from the client and server for 100 seconds, reporting results every 10 seconds. iperf – c servername – b 100 Kb. Performs a TCP upload from the client using 100 kb/s Iperf is a command-line tool that allows you to test the bandwidth, any way you like. Unlike online speed tests, you have to provide both server and client. In other words, when doing an online speed test, you connect to a server on the Internet, owned by the provider of the test (like Ookla).

First on the iPerf test results, so the iPerf test results is measuring the throughput in the TPC/IP layer and it measures the actual data traffic. For that reason it will always be lower than the Physical traffic rate as it effected by the headers (from WLAN till the IP headers) and all Acknowledgement frames (both WLAN Ack frames and higher Differences between iPerf2 and iPerf3 | NetBeez Network iperf – c servername – t 100.
