At ESUG georg Heeg made an interesting point, he showed that in VW  
loading an st file over 1000 only 1 was actually the compiler works  
(I do not remember exactly the ratio but it was striking). They  
aggressively optimized the loading and (removed the refreshing of  
RB.....).

So this was really making me think that speed is still really again  
an issue and that good optimized libraries are cool
even on our fast machines because we could do even more.

So this is clearly a good argument for do: :)
