Some of them are resolved, and some of them remain as theoretical issues. It turns out that the distance between the green line and the purple line in this graph: https://metrics.torproject.org/network.html?graph=bandwidth&start=2010-12-17&end=2014-03-17#bandwidth is way more influential on performance than we had realized. That is, we can mask many of the underlying technical questions by having enough capacity in the network. But it remains the case that too much bulk traffic can really hose the network, so it's still the case that people shouldn't do that. I haven't gotten around to organizing everything into a "Why else is Tor slow" document, to go with the first one: https://blog.torproject.org/blog/why-tor-is-slow But you can read some notes here: https://trac.torproject.org/projects/tor/wiki/org/roadmaps/Tor/Performance http://freehaven.net/~arma/tor-performance-outline.txt In that last URL I tag five promising directions with '*'. With some work, you can find papers corresponding to most of them at http://freehaven.net/anonbib/ > Btw. Would anyone send some stickers to give away to austria?
