Hi folks, I'm on a quest to find the average circuit-creation rate of clients. I looked in path-spec.txt to find an answer, but it wasn't there. So I thought: lets take some measurements using ARM. This got me some strange results. I start ARM, do some browsing, and close my browser. During the br

Hi Georg, I think the behavior you see can be explained by an overloaded download server. From the initial downloads graph you can see that there are on average 80.000 downloads a day. From the update pings and update requests graphs you can estimate that there are about 800.000 active Tor browser
