First, many thanks for putting this tool together and sharing it. It has proved invaluable over the years when dealing with ISPs.
That being said, we regularly encounter ISPs that don't think their network has issues. Most of the time we can pinpoint to a switch or connection that is over saturated. I would love to see a feature that allowed us to set a starting throughput, incremental step up/down throughput, and interval. This would help find the point at which issues begin. Here is the idea: iperf3 -c 192.168.1.100 -bt 1M -et 10M -st 10s -t 100 -u -bt = beginning throughput -et = ending throughput -st = step up/down time The thinking is that iperf3 would start a test (UDP or TCP) at 1Mb/s throughput, and then ramp up in 1Mb/s steps ever 10 seconds. This eliminates the need to do individual runs with different settings. Thank you, Craig Reeves
