Hi Dave,
'but folk in the 3rd world, (like, rural America) will love it.'
You know this, but for folks in the game since after the cold war ended. 3rd
world denotes states that are neither 'affiliated' to the 'western' USA-lead
block or to the the USSR-lead Warsaw-block states. The meaning as

I think 'Flent’s default sampling rate is too low' has a conceptually simple
solution, record dats at high sample rates and optionally downsample before

Hi Pete,
you could also try different packet sizes for you probes. The size ratio should
give you an idea about the RTT difference explained by simple transit times and
anything on top of that might be related to queueing. I am probably severely
underestimating the scope of your question, but I

Hi Toke,
I made the mistake of updating both my os (from macos 10.12.6 to 10.13.3) and
flent (to 1.2 I believe) at the same time. Now when I try to actually run a
test I get the following results:

Hi,
I believe you need to set the step size to something bigger:
from "run-flent --help"
-s STEP_SIZE, --step-size STEP_SIZE
Measurement data point step size.
For a slow link there are simply no data from netperf for a given "sampling"
point and hence you get the intermit
