Hmm, this type of test doesn’t really seem to have much connection to the
average Tor user. Middle relay <-> middle relay connections may be mostly
servers, but residential/mobile connections in Russia/Iran/China likely don’t
perform quite the same. Worse still, BBR can have measurable effects o
Cool! What did your testing rig look like?
I suppose the real question is what does the latency/loss profile of the
average Tor (bridge) user look like?

A few years ago I've got a dedicated server from one of these cheap French
hosts, which appeared to have a congested uplink (low-ish upload speeds).
Since the support was not able to solve this, b

In my experience it does work very well on Tor relays, and also on servers in
general (keeping in mind that these TCP congesti

I can’t find good in-practice analysis of this), BBA should han
