How much worse?
During the Montreal tor dev meeting I counted 1947 circuit build failures. https://lists.torproject.org/pipermail/tor-project/2017-October/001492.html
And where did you scan *from*?
I scaned from a server in the Netherlands.
(It's hard to interpret the results without the latency and quality of your client connection.)
I can record latency. What do you mean by quality? I mean... I'm not using these circuits to actually send and receive stuff.
Also, we have just deployed defences to exactly this kind of rapid circuit or connection building by a single client. I wonder if your client triggered those defences. The circuit defences would likely cause timeouts, and the connection defences would likely cause failures.
aha! That might explain the terrible results, hopefully it's not that network health has gotten worse in the last six months.
I also wonder if your client triggered custom defences on some relays.
I doubt it. I am not making sequential circuits to the same relays. The relays choosen for each circuit builds are generated from a shuffle.
You might get better results if you scan more slowly. Try to stay under 1 circuit every 3 seconds to each relay from
OK. I will try this. The scan will take longer but hopefully produce more accurate and useful results.
your IP address. Try to stay under 50 connections to the same relay from your IP address.
hmm OK. I can limit the number of concurrenct circuits that are being built but I do not believe that txtorcon let's me control the number of "connections" that little-t tor makes.
I'm going from memory, check the Tor man page, dir-spec, and the consensus for the latest DDoS parameter values.
