Depends how you define approximation, margins. I dropped them and calculated reiser4 needs the most CPU time. Hans wrote it's worked on. However guessing performance on a whatever carefully chosen loaded system from results on an unloaded system is exactly that, guess, not fact. > That's why it's misleading to draw conclusions from the CPU percentage alone. I've never wrote I made my guesses from the CPU percentage alone, you explained correctly why. I encourage you too to calculate yourself how much more CPU time reiser4 needs. Szaka
