> . . . And it doesn't even measure residual capacity exactly, because of
scheduling and fairness. For example, if my relay is operating at 100%
link utilization and TorFlow tries to measure it, TorFlow isn't going to
get 0 bandwidth and it isn't going to get 100% bandwidth; TorFlow is
probably only going to get roughly 1/N of my bandwidth where N is the
number of other active flows.
Excellent point! I had not considered this previously.
