If by "darknet" you mean Tor hidden services, then exit relays are not used. The circuits are client->guard->middle->middle->middle->middle->guard->hidden service. The bandwidth bottleneck for hidden services is probably guards, because all relays can be used as middles. Because relays with the Exit flag are used exclusively for exiting (due to the position weights [0], e.g. Wgd/Wed/Wmd), an estimate of the guard bandwidth is the weight of those with only the Guard flag, or ~40Gbps.
