No doubt about it. But the >SMP in DF doesn't work. Plain and simple. Here is a question for you: can you do a one-processor search for exactly 1 minute and see how many nodes it searched? (ignore knps stuff). Then do a two-processor test and again see the total nodes searched? Compare those two numbers. If SMP is working, they should be almost exactly doubled. (note that this is not 2x faster because some of those nodes are searched but were not necessary). I have a hell of a time getting my NPS value to display right on windows. I don't know why. But my nps value is always screwed up, probably due to the elapsed time that I use to compute the number...
