 Discussion in #tor-dev:

 {{{
 06:32 < nickm> athena: neat. I've been reading it and I hope Yawning has
 too
 06:32 < nickm> athena: have you looked at rob's experimental results that
 he
                asked about?
 06:33 < nickm> (See #12889)
 06:37 < nickm> I wonder what we should suggest that Rob try next
 06:37 < nickm> And how we can find out if this is a bug, or as-intended,
 or what
 06:39 < athena> the most interesting thing that comes to mind is varying
 the
                 thresholds
 06:40 < athena> in particular, in the limit of very high thresholds the
 behavior
                 should converge to something like the old behavior, modulo
 maybe
                 a little higher latency for triggering the new mechanism
 through
                 libevent and all
 06:41 < athena> if the gap persists even when the global high/low water
 marks are
                 set so high we start sending as soon as a circuit has
 anything
                 to send, we're basically scheduling one circuit at a time
 like
                 without the global scheduler
 06:42 < Yawning> hmm
 06:43 < nickm> there's also the possibility that something is going on we
 don't
                expect.  I wonder how we can figure out which.
 06:43 < nickm> and/or confirm your hypotheses above
 06:43 < Yawning> run the case athena just suggested and see if the
 behavior is
                  what we expect?
 06:43 < nickm> hm.  Plausible.
