A tool to measure network performance
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 bandwidth, 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 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.

- update to 3.12:
* cJSON has been updated to version 1.7.15 (#1383).
* The --bind <host>%<dev> option syntax now works properly (#1360 /
* A server-side file descriptor leak with the --logfile option has
been fixed (#1369 / #1360 / #1369 / #1389 / #1393).
* A bug that caused some large values from TCP_INFO to be misprinted
as negative numbers has been fixed (#1372).
* Using the -k or -n flags with --reverse no longer leak into future
tests (#1363 / #1364).
* There are now various debug level options available with the
--debug option. These can be used to adjust the amount of
debugging output (#1327).
* A new --snd-timeout option has been added to set a termination
timeout for idle TCP connections (#1215 / #1282).
* iperf3 is slightly more robust to out-of-order packets during UDP
connection setup in --reverse mode (#914 / #1123 / #1182 / #1212 /
* iperf3 will now use different ports for each direction when the
--cport and --bdir options are set (#1249 / #1259).
* The iperf3 server will now exit if it can't open its log file
* Various help message and output fixes have been made (#1299 /
* Various compiler warnings have been fixed (#1211 / #1316).
* Operation of bootstrap.sh has been fixed and simplified (#1335 /
* Flow label support / compatibility under Linux has been improved
* Various minor memory leaks have been fixed (#1332 / #1333).
* A getter/setter has been added for the bind_port parameter
(--cport option). (#1303, #1305)
* Various internal documentation improvements (#1265 / #1285 / #1304).
