Thanks - that actually looks like a very interesting piece of the whole puzzle. My whole is not that we shouldn't try to optimize anything. Sorry if that came across that way. The point is that despite a fairly wide-spread belief I've seen in the forum that utilizing multiple cores better is a cure for everything, I suspect that won't help for a large class of cases at all. Call it expectation management. And that we shouldn't lose sight of other bottlenecks. (I'd still like to have more good test data though...) Cheers, * Thorsten |
