So after long deliberations I have decided to write this article about iperf. Let me preface this with a statement that I like iperf very much and use it very often as it has many valid uses. You can find loads of tutorials on how to use it all over the internet but this article has very different aim.Here I would like to explain proper use-cases of this tool and some limitations and caveats one should be aware of while using software based testing (which iperf is prime example of). There are many version of iperf in the wild but the topics discussed below are valid for all of them to some degree.
