Also, more processors doesn't SPLIT costs, it multiplies them since more power is presumably available for more work. Since a single unit of work can only take advantage of a single engine, then costs should have no bearing. Same service consumed regardless. <SNIP> Since what I have said is so ridiculous, why don't you take a crack at answering the original question? Then we can all take pot shots at what you say, pointing out that the example you used, based on a real system, is absolutely _____ [fill in the blank].
