ESnet (Energy Sciences Network) is proud to announce the availability of

iperf 3.13.  This release is primarily a bugfix release. More information can 

be found in the iperf-3.13 release notes, which are contained in the RELNOTES.md

file in the distribution.

iperf 3.13 should be fully backward-compatible with prior iperf3

releases, that is, iperf 3.13 clients and servers should interoperate

correctly with all 3.x clients and servers.

iperf3 is a tool for measuring the maximum TCP, UDP, and SCTP

throughput along a path, allowing for the tuning of various parameters

and reporting measurements such as throughput, jitter, and datagram

packet loss.  It is fully supported on Linux, FreeBSD, and macOS.  It

may run on other platforms as well, although it has not received the

same attention and testing.  Note that iperf3 is not compatible with,

and will not interoperate with, version 2 or earlier of iperf,

although the two versions can co-exist on the same hosts and networks.
