Been trying lately to tackle this little issue I have been having and cannot figure out. Also please bare with me as I try to explain what is going on. 20/2 cable connection. QOS and other loads off, speed tests from multiple sites are solid and even slightly over provisioned usually around 21/2.5. Did the expected and set both up and down limits to 90% of the rated 20/2 and not the speed test ratings to be safe. Everything else is default. The main case I have seen crop up is if I run a torrent or two, QOS picks it up properly as P2P but despite what else is using the connection, the torrent speed is drastically limited. Sometimes down to 50KB/s on well seeded torrents. Second I turn off QOS it picks back up and saturates the connection. This is with no other connection load. With QOS on and this issue occuring my bandwidth graph barely breaks 5mbit/s down. Turn off QOS and I see it jump again to near full speed. Tenda N60 router, tried both bwq518's Shibby fork and Shibby's own firmwares to the same effect. CPU load even with torrents and QOS going is really low, within .10-.15. 64MB ram with consistently about 40MB free. From a resource standpoint it seems to be humming along beautifully. And other than an odd VLAN configuration issue on clean nvram that is easily fixed, I haven't had any bugs to speak of. Is there anything else I am missing that could cause this? Is it supposed to work like this? Other QOS implementations I have run into all assume under normal conditions even P2P/Bulk class data can saturate a connection if nothing else is using it. Once something else takes priority like web, voip, or video, P2P/Bulk data backs off just enough for those applications to function.
