Hi!
Good to hear that you guys try to solve the problem of slow measured relays. For example when i measure my relay
40108FDFA40EDB013F7291F3B4DA3D412ED3A5EF
with the speedtest from tele2 i get about 90 MiB download and about 50 MiB upload but Tor measures it with about 15 MiB. Some of my relays are measured very accurate but other ones are measured with only about 1/5 of what my results are.
I read the sbws documentation about how the measuring process is working and i am curious about how the experiment is measuring relays.
if possible please publish a little more info about the experiment or at least the results somewhere. Thanks

I am planning on performing an experiment on the Tor network to try to
gauge the accuracy of the advertised bandwidths that relays report in their server descriptors. Briefly, the experiment involves running a speed test on every relay for a short time (about 20 seconds).
Thanks Rob!
For context, I asked Rob to do this experiment, because we know that the current bandwidth authority design is mis-measuring relays, but we don't know how wrong things are. Giving every relay a short burst of load should give us some insight into how much traffic that relay can handle, which will in turn tell us how much room for improvement there is in our bandwidth estimation.
And as a bonus, for this one time, fast relays should actually be consistently seen as fast, and the Tor network should be better balanced and the user experience should be better. If we like how it works, our follow-up task will be to change things so we get this result all the time. :)
