I don't think that's a valid interpretation of my results. Consider the
two cases where I achieved a significant performance gain by replacing

I've just spent a session optimizing performance of the weather dynamics
routines, and I have largely done so by analyzing the performance of
elementary Nasal function calls and making use of my findings (and also by
dispensing with the pretense of elegant coding).
I was rather gratified to see t
