Rasool: Can you suggest to this guy that he try a "quantum 300" for his 600kbit uplink? I totally agree with his use of a smaller IW, also. https://www.mail-archive.com/freebsd-net%40freebsd.org/msg51463.html As for his headaches with pppoe and other sorts of odd (e.g. DSL/ATM) framing, it's a real headache with soft shaping. HTB has infrastructure (in linux) to handle it properly, as does cake, but it's a PITA. Can this code be configured to run at physical line rates (10Mbit, 100, 1GigE), without a shaper? What is the effect?
