The question is, what do we want to tell home gateway builders?
We should tell them that forwarding IP flows from higher bandwidth links into much lower bandwidth links generally produces better results when queues are only large enough to handle common burst sizes without loss and no larger. Unnecessarily large transmission queues may introduce persistently and perversely high path latency on fully loaded low-bandwidth links, producing severe negative effects on application throughput.
Beyond that, I don't know what else we should say. Maybe it would help to give some guidance for various common sub-IP links.
