I think the other point is that its only the cycle used for the Energy ratings that necessarily runs to those times.
The cycle on my Miele that is tested is the Energy Save cycle, which has no sensor wash, limited temperatures, limited consumption of 12L and a fixed time of 2:36. The Extra quiet cycle at 40 db runs for 4:30.
The Sensor wash can be done in as little as 70mins and uses up to 17L of water.
So whilst there might be long cycles, they're probably only there to satisfy the energy requirements and any good dishwasher should provide some quicker alternatives.
