Comment (by dgoulet):

 That is quite impressive results...

 So for some reasons, in the Netherlands, everything is the same time to
 extend to whatever hops but then it increases by a factor of 2 for US and
 then to some crazy values for HK... huh...

 If this was a problem within little-t tor, I would have expected to see
 the .nl with a longer latency as well....

 The big difference I can see is that the first graph is `client -> relay`
 where the rest is `relay -> relay`.

 Suggestion: is there any chance you can run your Onionperf _from_ a relay
 IP just to rule out some sort of traffic shaping for `client->relay`
 versus `relay->relay` connection only based on the source IP? Then I think
 we might want, again if possible, try with `client->bridge`?
