perfSONAR User Q&A and Other Discussion

The -I option didn't work, but using -T with iperf3 did. Here are the results:

Subject: Re: [perfsonar-user] bwctl speed questions

Brian: What latency is the path you are testing? Does owamp show any packet 
loss on that path?

Try doing a test with iperf3, which will give you TCP retransmit  count.

bwctl -c hostname -I iperf3 -i1 -fm -x -t20
