-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 tool for measuring the achievable TCP, UDP, and SCTP
+throughput along a path between two hosts.  It allows the tuning of

-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.
+iperf3 is a new implementation developed from scratch at the Energy
+Sciences Network (ESnet).  Among its goals were a smaller, simpler
+code base (compared to its predecessor, iperf2) and a library version
+of the functionality that can be used in other programs.  Note that
+iperf3 does not interoperate with with iperf 2.x.
