No, it’s just about flow completion time (“The actual transfer”) above being a function not only of the queue length, but also of the capacity the flow gets to use. Hence the push for a larger initial window. >> Flow completion time has to do with saturation as well. > > FCT was not a subject of that draft. Right - sorry for side-tracking. > My (admittedly ranty) points were: I read them - I didn’t want to get into this debate, it was only a side comment about not all flows being limited, and there being some value in better capacity usage too.
