That question comes up from time to time. I don't know the answer, and I
surely would like to know more.

I cannot believe that there ever will be a point in time where all our
hundredthousands of users are unable to saturate the Tor network . When
you use Tor, you can clearly see it could use more speed. And that's not
only the latency of 3 hops.

The last time I ran the script to generate the tormap for Google Maps,
only around 80 exits were faster than 1 mb/s. That includes a number of
"more logical Tor nodes on one physical line because Tor does not
scale", and many exits who only allow a very limited set of ports to exit.
One should be aware that being an exit relay is no different from being
a middle relay, only *additionally* allowing traffic to exit. So even if
exits were not the bottleneck, they should still be used as middle and
entry nodes.
