Hello gents, welcome your insight. (edit: title has a typo.. should read RT-N16) I have an ASUS RT-N16 rev1 running stock Tomato USB (Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB vpn3.6) which runs beautifully with QoS enabled with my 80Mbps downstream. Typically I see about 40-60% CPU utilization on the sirq mostly. If I flip to any derivation of Tomato USB, toastman, shibby, etc... and max my downstream (not torrents, but usenet/nzb) my sirq hits 100% and 1/5/15 goes through the roof... The situation improves on the mod based firmware, if I reduce my throughput to about 40Mbps. It appears only the stock Tomato USB is capable of managing QoS at 80Mbps. Any ideas on how I could resolve this, or is it simply a limit I cannot avoid? Thanks in advance.
