yup. particularly bad at the edges...
Anyhow, I looked around for some recent studies on the Tor network about such congestion issues but I can't find any information on if this phenomenon is observed on the Tor network.
Someone knows about that?
there are half a dozen papers on the topic in anonbib: http://freehaven.net/anonbib/topic.html
and alternate proposals like IPsec telescopes and DTLS transports with end-to-end congestion control/avoidance specifically to avoid queuing at intermediate hops.
i'm not aware of research on AQM applied to low latency anonymous networks, but i'm not up to date on the latest research :)
