Yes, I did, I even read Vandervoorde and Josuttis "C++ templates"  
(though I havent grasped all the concepts yet ;o) )

What I meant was "are the results not that good because of any of the 
functions I am using (element_prod in particular, since its quite new)?"
But I've got my answer, thanks! I didnt think the optimizer would do 
such a "bad" job for such a small formula. Lets hope gcc catch up 
quickly!
Sorry, I forgot to mention my config: gcc 3.1, OSX and G3 800 
(definitely not as fast as yours!!)

Thanks again
