If you can, I suggest finding other well connected hosts and using IPERF in
UDP mode for your testing. Separating TCP long-fat pipe and slow start
issues from true packet delivery/loss rates at a given bitrate are
beneficial. Use Linux as most iperf windows builds are based on cygwin and
have issues at higher bitrates.
