If the RTT is set to > 100ms (the default), you'll only get a limit of 12.5 MB=85 Yes, while trying to be funny I glossed over that part a bit = (the loooong RTTs part was aiming at that), sorry. But really I am = wonder what it is that makes my position that cake should expose and = honor a packet limit for its queueing so controversial; I am totally = happy with cake automatically selecting a good default automatically = using all information it has available, like configured bandwidth and = RTT, all I want to avoid the situation where cake divined something that = is totally consistent within the information it has available, but is = obviously wrong given additional information out of cake=92s control = (like total memory size or even maximum memory size the user is willing = to put aside for cake). I think cake=92s goal of being simple to use is = commendable, but we should make sure we do not accidentally end up with = cake being simplistic=85 (rather make the normal things easy/simple and = complex/crazy things possible ;) ) Best Regards Sebastian >=20 > Now, there is still an issue to be resolved in "unlimited" mode.
