Iperf: Iperf is an open source networking tool used to measure throughput or performance of a network. It can be used to test TCP and UDP. Iperf can be used in Windows, Linux, and MAC etc operation system. Intention of this article: There are different versions of Iperf, we will only focus on Iperf version 2.+ only.

iPerf - The TCP, UDP and SCTP network bandwidth
Iperf is much more reliable in its test results compared to many other online network speed test providers. An added advantage of using IPERF for testing network performance is the fact that, it is very reliable if you have two servers, both in geographically different locations, and you want to measure network performance between them. Jan 26, 2013 · Ran iperf and noted the 200 plus Mbits, then I copied a 3 gb file from the server to my desktop. Ran iperf again and what I'm calling the return speed (correct me if I'm wrong) is dismal at 13.4 Mbits. The way I interpret the results, good speed to the server, poor speed back from it. Main question. Am I misinterpreting the results? Oct 08, 2019 · Iperf is a command line-only tool that is used to diagnose network speed issues. Iperf measures the maximum network throughput a server can handle and reports the results back to you. If you start iperf client in reverse mode, iperf server will send data and iperf client will receive. In such case results we got during the test: [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 569 MBytes 478 Mbits/sec sender [ 4] 0.00-10.00 sec 569 MBytes 478 Mbits/sec receiver Jun 01, 2018 · iPerf is a command-line tool used in diagnosing network speed issues by measuring the maximum network throughput a server can handle. It is particularly useful when experiencing network speed issues, as you can use iPerf to determine which server is unable to reach maximum throughput. Dec 23, 2019 · Important: From the benchmark results, as shown in the above screenshot, there is a variation in values from the server and client. But, you should always consider using the results obtained from the iperf client machine in every test you carry out. How to Perform Advanced Network Test Throughput in Linux
