This is iperf 2.2.2, a tool for measuring network throughput, latency and
responsiveness over TCP and UDP.

iperf 2 and iperf 3 are separate programs and DO NOT interoperate: use the
same one at both ends of a test.

Documentation:
  man iperf (after make install), or man/iperf-manpage.html

An Android client is also available, on Google Play and as an APK from
SourceForge. Its source is in android/; see android/README.md to build it.

Briefly:

Do one-time if needed:
  dnf install gcc
  dnf install gcc-c++
  dnf install automake
  dnf install make

then to build do:
  ./configure      -- configure for your machine
  make             -- compile Iperf
  make install     -- install Iperf, if desired, from root

Some useful options and targets:
  ./configure --enable-professional     -- professional edition, which adds
                                           features such as UDP L4S
  ./configure --host=x86_64-w64-mingw32 -- cross-compile, Windows in this case
  make check                            -- run the test suite
  make dist-all                         -- make the source tarball

and to use:
  iperf -s               (on machine "foo.bar.edu")
  iperf -c foo.bar.edu   (on some other machine)
  iperf -h               (for help screen)
  iperf -v               (for version information)
