Reorganize the README, and try to format it so it looks better when
it's displayed on the iperf page on GitHub. I wish there was a way to preview this change before pushing it.

iperf3: A TCP, UDP, and SCTP network bandwidth measurement tool
|
||||||
|
================================================================
|
||||||
|
|
||||||
iperf3 is a tool for measuring achievable bandwidth on IP networks.
|
Summary
|
||||||
|
-------
|
||||||
|
|
||||||
iperf3 is NOT backwards compatible with the original iperf.
|
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.
|
||||||
|
|
||||||
Supported platforms:
|
This version, sometimes referred to as iperf3, is a redesign of an
|
||||||
* Linux
|
original version developed at NLANR/DAST. iperf3 is a new
|
||||||
* FreeBSD
|
implementation from scratch, with the goal of a smaller, simpler code
|
||||||
* Mac OSX
|
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.
|
||||||
|
Note that iperf3 is NOT backwards compatible with the original iperf.

Primary development for iperf3 takes place on CentOS Linux, FreeBSD,
|
||||||
|
and MacOS X. At this time, these are the only officially supported
|
||||||
|
platforms, however there have been some reports of success with
|
||||||
|
OpenBSD, Android, other Linux distributions.

Invoking iperf3
|
||||||
|
---------------
|
||||||
|
|
||||||
|
iperf3 includes a manual page listing all of the command-line options.
|
||||||
|
The manual page is the most up-to-date reference to the various flags and parameters.
|
||||||
|
|
||||||
|
For sample command line usage, see:

||||||

||||||
|
http://fasterdata.es.net/performance-testing/network-troubleshooting-tools/iperf-and-iperf3/
|
||||||
|
|
||||||
|
Using the default options, iperf is meant to show typical well
|
||||||
|
designed application performance. 'Typical well designed application'
|
||||||
|
means avoiding artificial enhancements that work only for testing
|
||||||
|
(such as splice()'ing the data to /dev/null). iperf does also have
|
||||||
|
flags for 'extreme best case' optimizations but they must be
|
||||||
|
explicitly activated.
|
||||||
|
|
||||||
|
These flags include:
|
||||||
|
-Z, --zerocopy use a 'zero copy' sendfile() method of sending data
|
||||||
|
-A, --affinity n/n,m set CPU affinity
