 iperf is a tool for measuring the maximum TCP and UDP bandwidth along
 a path between two hosts.  It allows the tuning of various
 parameters and UDP characteristics, and reports bandwidth, delay
 jitter, datagram loss.  iperf was originally developed by NLANR/DAST.
 
 iperf3 is a new implementation from scratch, with the goal of a
 smaller, simpler code base, and a library version of the functionality
 that can be used in other programs.  iperf3 also a number of features
 found in other tools such as nuttcp and netperf, but were missing from
 iperf 2.x.  iperf3 is not backwards compatible with iperf 2.x.
