I agree the six-hop circuits > would be overkill for that; I wonder if the network slowdown you get BTW, I believe that the number of hops can be reduced below 3 on both sides (client/server). For Orchid, this will require a change to CircuitPathChooser. For other Tor implementations, it might require using the control port to custom-build a circuit.
