Hello, I am looking for ways to optimize several relay nodes to ensure maximum possible bandwidth consumption. The actual numbers I have are within 20-50 megabits in one direction per node (i.e. not the gigabit-scale tuning discussed in the FAQ). From what I can tell the Guard flag affects routed bandwidth very negatively. After getting the flag the bandwidth drops off sharply and a Guard node will typically push an order of magnitude (TEN times) less traffic than a non-guard one. This is confirmed by some blog and mailing list posts I found, mentioning that a node will have its traffic drop after receiving the guard flag. I wonder if can anything can be done about this. Can a torrc option be added to set that a relay never wants to become a Guard; can the algorithms be tuned so that Guards also keep receiving more 'casual' traffic (sorry if my understanding is not consistent with how this actually works); or as a brute hack should I reset my nodes' private key and fingerprint e.g. every couple of weeks (but ramping up from scratch takes a lot of time and may nullify any benefit from even doing so). -- With respect, Roman
