For two portions of white rice, the Cuckoo needs about 35 minutes. With the turbo function, it should take about 18 minutes according to the manual.

Yes, there is a quick programme that takes less than 20min.

There is no general answer because there are different programmes depending on the rice. Normal parboiled rice takes about 30-40 minutes. Glutinous rice a little shorter and wholemeal rice about 50 minutes. There is a quick function for glutinous rice. But I have never tried it.
