Right now Tor directories track consensus download times, and put that in
their extrainfo descriptors.
It would be useful to have this info broken down per country, so we can
e.g. learn when vanilla Tor starts getting throttled in a particular
country (like it did a few years ago). And hey, for obfs4 bridges, it
would be neat to compare if they are able to deliver the consensus quickly
when vanilla Tor isn't.
I don't think we should put per-country performance stats into extra-info
descs here, mostly since they'd get too big. I also briefly considered
saying "well I only care about these two countries, so let's put only
those in the extrainfo descs", but I think that's not a great strategy
either.
So I think the current goal for this ticket is to produce an easy patch
for relay operators to use if they want to measure this data, and also to
either make this patch sufficiently safe that we're ok if relay operators
want to apply it -- or convince ourselves that it is too unsafe and it
should not be used.
