ESnet (Energy Sciences Network) is proud to announce iperf-3.1b3, the
third beta release from the iperf 3.1 codeline.  This beta release is
intended for testing by early adopters, and should not be packaged in
any operating system distributions.  We're particularly interested in
reports of any regressions from the 3.0 codeline; we aim for the
official iperf 3.1 release to be at least as good with respect to code
quality as the most recent 3.0.x release.

iperf-3.1 adds support for tests using SCTP on FreeBSD, Linux, and
Solaris.  In addition, it improves support for some optional features
on FreeBSD, and in general increases compatibility with a number of
other operating systems.  Finally, a number of minor bug fixes and
enhancements have been added.

This third beta release fixes some problems with RPM generation.  It
is functionally identical to iperf-3.1b2.

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.
