Easily deployed on your system.
The application doesn’t need to be installed; the EXE file that it comes packed in is portable, which means it doesn’t affect your computer registry. Being a command line utility, it can only run from a command prompt window.
Thorough help provided
In order to learn about its usage, just run the application followed by the argument ‘-help’. Notice how the program features several individual options for Client and Server specific settings, as well as for Client and Server configurations altogether.
Put your bandwidth under the scope
A quick summary of Iperf’s capabilities includes first of all, the possibility to report bandwidth parameters, MSS (maximum segment size) details, packet loss and delay jitter measurements and multicast support.
Manage more connections at a time
Also worth mentioning is its ability to handle multiple connections from both the server and the client. In addition, you can set it to run for a user-defined period of time instead of placing a restriction on the amount of transferred data.
Other settings include selecting the unit of measurement (Kilobits or Kilobytes, Megabits or Megabytes), reporting error messages, setting domains to IPv6 and running it as a Windows service.
Requires advanced dedicated knowledge
Even though it may seem simple and accessible, Iperf was designed for advanced users. Proper usage requires network and server knowledge; the help section is only useful to those accustomed to terms specific to TCP / UDP monitoring. However, users who can understand its ways can get detailed reports regarding bandwidth performance.
Taking everything into consideration, we can say that Iperf can come in very handy for network administrators who constantly need to keep an eye on bandwidth performance. Even though it is but a command line, it manages to provide powerful assistance when it comes to tweaking.
