+iperf3: A TCP, UDP, and SCTP network bandwidth measurement tool
+================================================================
+
+Summary
+-------
+
+iperf is a tool for active measurements of the maximum achievable
+bandwidth on IP networks. It supports tuning of various parameters
+related to timing, protocols, and buffers. For each test it reports
+the measured throughput / bitrate, loss, and other parameters.
+
+This version, sometimes referred to as iperf3, is a redesign of an
+original version developed at 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 has a number of features found in other tools
+such as nuttcp and netperf, but were missing from the original iperf.
+These include, for example, a zero-copy mode and optional JSON output.
+Note that iperf3 is *not* backwards compatible with the original iperf.
+
+Primary development for iperf3 takes place on Ubuntu Linux, FreeBSD,
+and macOS. At this time, these are the only officially supported
+platforms, however there have been some reports of success with
+OpenBSD, NetBSD, Android, Solaris, and other Linux distributions.
+
+iperf3 is principally developed by ESnet / Lawrence Berkeley National
+Laboratory. It is released under a three-clause BSD license.

+
+Obtaining iperf3
+----------------
+
+Downloads of iperf3 are available at:
+
+ https://downloads.es.net/pub/iperf/
+
+To check out the most recent code, clone the git repository at:
+
+ https://github.com/esnet/iperf.git
+
+Building iperf3
+---------------
+
+### Prerequisites: ###
+
+None.
+
+### Building ###
+
+ ./configure; make; make install
+
+(Note: If configure fails, try running `./bootstrap.sh` first)
+
+Invoking iperf3
+---------------
+
+iperf3 includes a manual page listing all of the command-line options.
+The manual page is the most up-to-date reference to the various flags and parameters.
+
+For sample command line usage, see:
+
+https://fasterdata.es.net/performance-testing/network-troubleshooting-tools/iperf/
+
+Using the default options, iperf is meant to show typical well
+designed application performance. "Typical well designed application"
+means avoiding artificial enhancements that work only for testing
+(such as splice()'ing the data to /dev/null). iperf does also have
+flags for "extreme best case" optimizations, but they must be
+explicitly activated.
+
+These flags include:
+
+ -Z, --zerocopy use a 'zero copy' sendfile() method of sending data
+ -A, --affinity n/n,m set CPU affinity
+
+Bug and Security Reports
+------------------------
+
+Before submitting a bug report, please make sure you're running the
+latest version of the code, and confirm that your issue has not
+already been fixed. Then submit to the iperf3 issue tracker on
+GitHub:
+
+https://github.com/esnet/iperf/issues
+
+In your issue submission, please indicate the version of iperf3 and
+what platform you're trying to run on (provide the platform
+information even if you're not using a supported platform, we
+*might* be able to help anyway). Exact command-line arguments will
+help us recreate your problem. If you're getting error messages,
+please include them verbatim if possible, but remember to sanitize any
+sensitive information.
+
+If you have a question about usage or about the code, please do *not*
+submit an issue. Please use one of the mailing lists for that.
+
+If you suspect there is a potential security issue, please contact the
+developers at:
+
+iperf@es.net
+
+Relation to iperf 2.x
+---------------------
+
+Although iperf2 and iperf3 both measure network performance,
+they are not compatible with each other.
+The projects (as of mid-2021) are in active, but separate, development.
+The continuing iperf2 development
+project can be found at https://sourceforge.net/projects/iperf2/.
