ESnet (Energy Sciences Network) is proud to announce the release of
iperf-3.16.

This version of iperf3 introduces a major change in the way that
parallel tests (specified with the -P/--parallel flag) are
handled. iperf3 now uses a separate thread (pthread) for each test
stream. Generally multiple threads will use multiple CPU cores (if
available), so this change will likely improve iperf3's ability to do
higher-speed tests, particularly on 100+Gbps paths. This version has
recorded transfers as high as 148Gbps in internal testing at ESnet
over 200Gbps paths.

This release also includes a few other minor changes for OpenSSL
support. More information on those changes can be found in the
iperf-3.16 release notes, which are contained in the RELNOTES.md file
in the distribution.

iperf-3.16 should be fully backward-compatible with prior iperf3
releases, that is, iperf-3.16 clients and servers should
interoperate correctly with all 3.x clients and servers.
