I for one find SWBS unimpressive. There are known bugs in both bandwidth authority implementations, sbws and torflow. Here's a list of the critical sbws bugs: https://trac.torproject.org/projects/tor/query?status=!closed&keywords=~sbws-majority-blocker We're working on getting some funding to fix these bugs in sbws. (Torflow is very old and hard to install, most of its dependencies are unsupported. So we aren't tracking torflow bugs in detail any more.) I don't think we've added any sbws instances for a few months. And I haven't seen any specific evidence that sbws (or torflow) is responsible for these issues. If you give us a timeframe, we might be able to help more. It's also possible that there are more exits in the Tor network, or that the routing between the bandwidth authorities and your network has become slower. There are some other common explanations for slow relays, listed on this wiki page: https://trac.torproject.org/projects/tor/wiki/doc/MyRelayIsSlow You might find some of the tips on that page helpful. Also, if you can find some authorities that are giving your relays low measurements, we might be able to find out why. You can see a copy of all the bandwidth authority measurements here: https://consensus-health.torproject.org/consensus-health.html T -- teor ----------------------------------------------------------------------
