*+ 1* I did a 2-million link test, i.e. 1 million in, 1 million out, spread evenly over 100 connections -- on a single router, coming from a single client -- using Gordon's python client made for this purpose -- and nothing blew up or melted down. And it did not use an exorbitant amount of memory like it used to before Gordon's fix, nor did it slow down linearly as the number of links increased.
NOTE that the router does become unresponsive while all those links are being torn down -- i.e. it does not respond to qdstat calls -- but that is not a regression and the fix is believed to be in Proton code, not in the router. This is significant, because it is easy for the user to conclude that the router has simply crashed while it is not responding. A fix for this issue will hopefully be in the next release.
