ESnet (Energy Sciences Network) proudly announces the public release
of iperf-3.0.7.  This version is a maintenance release with a several
fixes and enhancements.  Notable among these are fixes for a bug that
made it possible to disrupt existing, running tests and another bug
that caused problems with running iperf3 within perfSONAR.

More information on changes can be found in the RELEASE_NOTES
file in the source distribution.

iperf3 is a tool for measuring the maximum TCP and UDP performance
along a path, allowing for the tuning of various parameters and
reporting measurements such as throughput, jitter, and datagram packet
loss.

The original iperf was implemented by NLANR / DAST.  Version 3 is a
complete reimplementation, with the goals of a smaller, simpler code
base, and a library that can be used by other programs.  It also adds
new functionality, such as CPU utilization measurements, zero copy TCP
support, and JSON output.  Note that iperf3 clients and servers are
not compatible with, and will not interoperate with, earlier versions
of iperf.

iperf3 is fully supported on Linux, FreeBSD, and MacOS X.  It may run
on other platforms as well, although it has not received the same
attention and testing.
