I'll give this a try, but I wouldn't say that the metrics team is your best bet here. We're busy providing all the data, but we're spending way less time on looking at it than you would expect.
Firstly, while we don't have (public) datasets showing this, I am fairly certain that the public meek bridges have their bandwidth capped (to limit costs) and raising that cap would directly improve the speed of meek users. (Implying that the bottleneck the majority of the time is the meek transport.) Right?
That's also my intuition, but I don't have the data you're looking for. David would know better.
Secondly, I know it's too simplistic to say "Our exits are operating at 85% of capacity, our guards are 65% and our middles at 40%" (for a host of reasons, including guard/middle overlap) but how close can we get to something simple that demonstrates more exits will help the (non-bridge) network the most? (If that is in fact the case!)
I don't know an easy answer to this, but you could look at consensus bandwidth weights for a start: https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n2699 The latest consensus bandwidth weights are: bandwidth-weights Wbd=0 Wbe=0 Wbg=4127 Wbm=10000 Wdb=10000 Web=10000 Wed=10000 Wee=10000 Weg=10000 Wem=10000 Wgb=10000 Wgd=0 Wgg=5873 Wgm=5873 Wmb=10000 Wmd=0 Wme=0 Wmg=4127 Wmm=10000 If you go add many more guards or exits, you should observe how those weights change. You could also ask Mike for more details.
I might have more questions to relay, but for now these seem to be the main ones.
Sounds good. You should also ask relay operators on the tor-relays@ mailing list. Though asking on this list is a good start, too. All the best, Karsten -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQEcBAEBCAAGBQJYfkIgAAoJEC3ESO/4X7XBnYoH/Rt4SO9vjY56oTPO77X3cUeI r59L0aCU/8gaHxvdGecraJGrIYsIW/Nq8y+88NosZeONH8dSFU9FL2ifnKF88rFB 0CCp7+JHGb9M3nmSvyFXMgDsOlYEc/4EHyE7ykqp2F/FuxRV/0TkNz32kJNZNtV8 /sXIZ0BN7I3L6pT0YGAOh21MZ2mxb0rKd3Sm4QT45ZwPZQFXQXbPg9Xfls7dKc5g dObhrLv9UO0od3/+FXEDf1MIG3pnTwJFEdGer02iGJAFYPkIghYGOCM9nIzI2BrJ XA/fhAa2MgiEGJz8D3jLbbq9NKrrap5wAtsHWHhafRAtBUYBGdsYtjU3G7O+dRc= =Fjqx -----END PGP SIGNATURE-----
