If anyone needs a per-compiled iPerf.exe, no need for cygwin libraries, lemme know. It's a great tool!

iperf might be able to do what you need and there are Windows builds available, but I'm not sure if it has a mode where it's not flooding the network trying to test maximum speed.

In UDP mode, iperf sends at 1 Mbps by default. You change the rate with the -b flag. There's an iperf-2.0.5-cygwin build floating around for Windows.
