Hello,
We've been exploring dynamic algorithms for throttling Tor clients. We've come up with three algorithms that are easier to maintain than static throttling (i.e. don't need to be reconfigured often), and produce significant performance benefits for web clients at the expense of bulk clients. Details are available in our technical report:
http://www-users.cs.umn.edu/~jansen/papers/throttling-umntr11-019.pdf
We are looking for feedback and are wondering if these algorithms look useful to Tor. They have already been implemented, and patches can be prepared if there is interest.
Best regards, Rob
