But in this example of qRem the time is almost so as if quot was not computed. Probably, the coefficient of this expense is small.

On the other hand, an extra memory occupation also often causes slowing down of all the environment program, because this occupation approaches garbage collection.

Use "./Main +RTS -s -RTS" to find out how hard the garbage collector has to work. Use "./Main +RTS -M64m -RTS" to find out how much memory is not enough. We are speaking of "snd (qRem n 5)", of course. ("64MB ought to be enough for everybody."? :) )
