It was verified with 8 of my experimental nodes, and I believe Moritz had quite a bit of difficulty getting to that level as well. However, it would be great if we could get some hard data on how long it has taken all of our fastest nodes to acquire data. If someone were to write a script to process descriptor archives to check how long it takes fast relays to ramp up, that would be really awesome. We'd then be able to see exactly what effect Guard, Middle and Exit node flags have on ramp up time: http://metrics.torproject.org/data.html > After about 24h the new exits blutmagie2, blutmagie3, and blutmagie4 I > placed in service this May got the same amount of traffic like the old > blutmagie. So rampup phase wasn't longer than one day. Two factors may explain this: 1. Your exit policy is also more permissive than the ones we use. We use: https://blog.torproject.org/blog/tips-running-exit-node-minimal-harassment +SILC+IRC+IRCS. The default policy will likely cause a lot more traffic to be pushed through your node due to P2P (ab)users. 2. If you reused keys, the bandwidth authorites would "remember" the speed of your new nodes, and immediately vote them faster, which would also helps a lot. It is only the very first appearance that takes a really long time. -- Mike Perry Mad Computer Scientist fscked.org evil labs
