Cool, I hope my experiment yields good results for your relay.

Note that I am not using sbws for this experiment, but rather a custom measurement process. The plan is to use multiple Tor clients to create multiple sockets to the target relay, and then each client will extend a circuit through the target and then back to one of a set of relays running on the same machine as the client. I'm hoping the use of multiple sockets will help mitigate the effects of packet loss.

The results will be published when possible, after they have been analyzed and understood.

Peace, love, and positivity,
Rob
