Comment(by arma):
This project is tricky for two reasons:
A) Only relays after 0.2.2.7-alpha respect these consensus params, so any
performance changes we see will be highly variable.
B) If we enable these params and they actually work, then the bwauthority
measurers are going to start thinking that relays are slower than they
are. Right now the bwauth scripts push more bytes over relays they believe
to be fast. They'll get throttled now. Worse, they'll only punish the
relays running 0.2.2.7-alpha or later, so those relays will get lower
weights in the consensus, see less use from clients, and look like they're
getting faster even if they're not. The short-term fix is to make the Tor
that each bwauth uses be a relay (but advertise very little bandwidth), so
it isn't throttled.
