Obtaining iperf3

Binary Distributions

Note that ESnet does not distribute binary packages of iperf3. All of the packages listed in this section are provided by third parties, who are solely responsible for their contents. This is an incomplete list of binary packages for various operating systems and distributions:

  • FreeBSD: via the FreeBSD Ports Collection with sudo pkg install benchmarks/iperf3.

  • Fedora / RedHat Linux / CentOS / Rocky: iperf3 and iperf3-devel in Fedora 19 and 20 and in Fedora EPEL 5, 6, and 7. iperf3 is included as a part of RedHat Enterprise Linux 7.4 and later (as well as CentOS 7.4 and later, and all versions of Rocky Linux), and can generally be installed with yum install iperf3.

  • Ubuntu: iperf3, is available in Trusty (backports), and as a part of the main release in Vivid and newer. It can generally be installed with sudo apt-get install iperf3.

  • macOS: via HomeBrew with brew install iperf3 or MacPorts with sudo port install iperf3.

  • Windows: iperf3 binaries for Windows (built with Cygwin) can be found in a variety of locations, including https://files.budman.pw/ (discussion thread).

Source Distributions

Source distributions of iperf are available as compressed (gzip) tarballs at:

https://downloads.es.net/pub/iperf/

Note: Due to a software packaging error, the 3.0.2 release tarball was not compressed, even though its filename had a .tar.gz suffix.

Note: GitHub, which currently hosts the iperf3 project, supports a “Releases” feature, which can automatically generate .zip or .tar.gz archives, on demand, from tags in the iperf3 source tree. These tags are created during the release engineering process to mark the exact version of files making up a release.

In theory, the .tar.gz files produced by GitHub contain the same contents as what are in the official tarballs, note that the tarballs themselves will be different due to internal timestamps or other metadata. Therefore these files will not match the published SHA256 checksums and no guarantees can be made about the integrity of the files. The authors of iperf3 always recommend downloading source distributions from the the directory above (or a mirror site), and verifying the SHA256 checksums before using them for any purpose, to ensure the files have not been tampered with.

Source Code Repository

The iperf3 project is hosted on GitHub at:

https://github.com/esnet/iperf

The iperf3 source code repository can be checked out directly from GitHub using:

git clone https://github.com/esnet/iperf.git

Primary development for iperf3 takes place on CentOS 7 Linux, FreeBSD 11, and macOS 10.12. At this time, these are the only officially supported platforms, however there have been some reports of success with NetBSD, OpenBSD, Windows, Solaris, Android, and iOS.
