We present the design and implementation of Shadow, an open-source software architecture for efficiently running accurate, large scale Tor experiments on a single machine. Using Shadow, we evaluate Tor’s EWMA scheduling algorithm, and show that, contrary to previous results on small networks, performance can decrease significantly in realistic deployments.
