Okay, does this stay fair if one of the hosts open a bunch of = websites at the same time? Does the download test also give per-host = fairness if the number of downloads is massively imbalanced between the = hosts? > However, when one of > the hosts is using bittorrent, he also gets most of the bandwidth, = i.e. > if total ingress bandwidth is 3300kbit, A is using bittorrent and gets > 2900kbit, B is downloading from a single website and gets 400kbit. Bit-torrent is a hard problem it seems, especially the cobalts = branch that you test is supposed to better deal with it though so this = is abit of a puzzle. How long are your tests? Are you looking only at a = few seconds or something like >30 seconds (maybe the shaper needs time = to reach equilibrium)? What happens in the upload during theses tests? I = also wonder how many new torrent connections are established during the = test or are the torrent flows long lived? I probably would try to instantiate cake not on the wan but on a = lan interface of the router and re-do the test without the =E2=80=9Cnat=E2= =80=9D option just to reduce the number of tested parts. If you should = do this, please remember that ingress and egress are per interface, so = downloads from the internet use the LAN-egress while internet-uploads = use LAN-ingress, so make sure to switch the bandwidth definitions for = your two cake instances accordingly.=20 Finally could you post the results of =E2=80=9Ctc -s qdisc=E2=80=9D= before, during and after your bit-torrent tests for the test you just = reported and the LAN test in case you ago that route.
