Hey John-Paul,
The “local” side, unfortunately, does not provide the data we need, because
the sending side of iperf can be nearly worthless on a lossy network, with a
large window size. I’m guessing there are few bwctl 1.4 instances out there,
but it’d probably be best to modify the RegularTesting parsing to handle the
old bwctl instances.
Cheers,
Aaron
