Note that iperf2 is no longer being developed by its original

maintainers. However, beginning in 2014, another developer began

fixing bugs and enhancing functionality, and generating releases of

iperf2. Both projects (as of late 2017) are currently being developed
|

actively, but independently. The continuing iperf2 development

New options:
|
||||
|
||||
-V, --verbose more detailed output than before
|
||||
-J, --json output in JSON format
|
||||
-Z, --zerocopy use a 'zero copy' sendfile() method of sending data
|
||||
-O, --omit N omit the first n seconds (to ignore slowstart)
|
||||
-T, --title str prefix every output line with this string
|
||||
-F, --file name xmit/recv the specified file
|
||||
-A, --affinity n/n,m set CPU affinity (Linux and FreeBSD only)
|
||||
-k, --blockcount #[KMG] number of blocks (packets) to transmit (instead
|

of -t or -n)
|

-L, --flowlabel set IPv6 flow label (Linux only)
|

|

Changed flags:
|
||||
iperf3 contains a number of options and functions not present in
|

iperf2. In addition, some flags are changed from their iperf2
|
||||
counterparts:
|

-C, --linux-congestion set congestion control algorithm (Linux only)

--bidir bidirectional testing mode

iperf3 Release Notes
|
||||
====================
|
||||
|
||||
iperf 3.8 2020-06-08
|
||||
--------------------
|
||||
|
||||
* Notable user-visible changes
|
||||
|
||||
* Profiled libraries and binaries are no longer built by default
|
||||
(#950).
|
||||
|
||||
* A minimal Dockerfile has been added (#824).
|
||||
|
||||
* A bug with burst mode and unlimited rate has been fixed (#898).
|
||||
|
||||
* Configuring with the --enable-static-bin flag will now cause
|
||||
a statically-linked iperf3 binary to be built (#989).
|
||||
|
||||
* Configuring with the --without-sctp flag will now prevent SCTP
|
||||
from being auto-detected (#1008). This flag allows building a
|
||||
static binary (see above item) on a CentOS system with SCTP
|
||||
installed, because no static SCTP libraries are available.
|
||||
|
||||
* Clock skew between the iperf3 client and server will no longer
|
||||
skew the computation of jitter during UDP tests (#842 / #990).
|
||||
|
||||
* A possible buffer overflow in the authentication feature has been
|
||||
fixed. This was only relevant when configuration authentication
|
||||
using the libiperf3 API, and did not affect command-line usage.
|
||||
Various other improvements and fixes in this area were also made
|
||||
(#996).
|
||||
|
||||
* Notable developer-visible changes
|
||||
|
||||
* The embedded version of cJSON has been updated to 1.3.17 (#978).
|
||||
|
||||
* Some server authentication functions have been added to the API
|
||||
(#911).
|
||||
|
||||
* API access has been added to the connection timeout parameter
|
||||
(#1001).
|
||||
|
||||
* Tests for some authentication functions have been added.
|
||||
|
||||
* Various compiler errors and warnings have been fixed.
