Groovy. I note that I am really fond of the linux "fdtimer" notion for tickers, we use that throughout the high speed stats gathering code in flent. I'd really like a voip or ping tool that used those, and I've always worried about iperf's internal notion of a sampling interval. On 9/20/16 3:00

[Bloat] iperf3 and packet bursts

2016-09-20 Thread Aaron Wood
We were using iperf3 at work to test a network path (we wanted the fixed-rate throttling that it can do). And while TCP would fill the 50Mbps link from the ISP, UDP couldn't. UDP couldn't get over 8Mbps of goodput, no matter what rate we specified on the command line. We found a 100ms timer
