Comment:

 I've
 [https://trac.torproject.org/projects/tor/attachment/ticket/4486/n23-2012-03-15.pdf
 attached a first set of results]. The Tor model is as described in #4086
 (where relay capacities in Shadow are based on their reported observed
 bandwidth in Tor).

 I ran a vanilla experiment, and an n23 experiment with the following:

 {{{
 UseN23 1
 CircuitWindowSize 1000000
 StreamWindowSize 1000000
 }}}
 Completed download counts may give us a sense of load on the network.
 vanilla:
 24148 320KiB (web)
 74 5MiB (bulk)
 n23:
 28767 320KiB (web)
 237 5MiB (bulk)

 I added the "window size hack" to my configuration, but ended up using the
 git version where that was presumably not needed. Would this cause any
 problems?
