Comment (by asn): Replying to [comment:4 teor]: > If you write down a list of exactly what you want to know, we can probably collect some stats on ~18 HSDirs using PrivCount. Hey teor, I might be hijacking this ticket by suggesting the following stats but here are some basic ideas: - How many v2/v3/both descs per HSDir? - How much total RAM do all v2/v3/both descs occupy on your hsdirs? (max,min,avg,mean over your 18 hsdirs) - Size variance of v2/v3 descs? (max,min,avg,mean) - What's the rate of incoming v2/v3/both descs? - How many failed requests for HS descriptors over time? (percentage over total requests?) These are just the obvious stats that I came up with. We can come up with more stuff as we see some results and understand the space better. Let me know if you need help in turning the above sentences into methodologies. > We will also need an estimate of how much 1 client / service would contribute to each statistic in 10 minutes. > Is that to figure out the noise for differential privacy? Let's try to come up with the final stats list and then we can figure this out. Should we make a separate ticket (child of this one) for this task? -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/24425#comment:5> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
