If memory serves, at the time there was a lot of concern about cpu usage and (I felt) that every line, every potential instruction and cache hit was being scrutinised. NAT lookup by default was deemed too much. Cake ended up being ‘cpu heavy’ though I’ve yet to see a better combination of shaper, aqm, flow fairness, host fairness, DSCP awareness and ack filtering in one overall package, let alone one that did it in less cpu.
