* component: Metrics/Statistics => Metrics/Analysis Comment: Replying to [comment:4 teor]: > Hey Karsten, thanks for the graph. It's good to see that most relays have a reasonable consensus weight to bandwidth ratio. > > But for a log plot, that spread seems a lot: in some cases, it looks like relays with similar advertised bandwidths get 10x the consensus weight. And we still think that bandwidth allocation isn't balanced geographically. From what people tell us, US East and EU West coasts get a large allocation, and it falls off from there. > > Can you show the important section of this graph (the high bandwidths and the high consensus weights) using a linear plot? I'm adding a linear plot below: [[Image(overweight-relays-non-log-scale-2017-11-08.png, 700px)]] Here's how I made it, using the attached CSV file: {{{ require(ggplot2) ggplot(o, aes(x = adv_bw, y = cw)) + geom_point(alpha = 0.25) + scale_x_continuous("advertised bandwidth") + scale_y_continuous("consensus weight") ggsave("overweight-relays-non-log-scale-2017-11-08.png", width = 8, height = 8, dpi = 150) }}} > Is there a way of showing the consensus weight to advertised bandwidth ratios on a map? Maybe as geolocated points? Not easily, and I'm afraid I'm juggling too many other things to dive into such a new visualization now. But maybe this is something where others can step in. Basically, all relevant data is available via Onionoo, including longitude and latitude of relays. I'm moving this ticket to Metrics/Analysis where we collect analyses like this one without having concrete plans to integrate results into metrics code. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/24045#comment:5> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
