sorry it was a my bad explanation, we are speaking about scheduling times. The 15% loss is relative at the same switch / second. The fact is that two tasks enviroments has a switch rate much lower then a 300 one, so the 15% loss must be scaled with a factor (2 / 300) << K < M, where M depend on the nature of the tasks ( system call rate versus pure computing ). I think it can be lower than 1%.
Cheers, Davide.
