Re: [boost] units: performance testing

Dear Martin,

Please look at the first line in the Boost Design and Programming  
Guidelines :

http://www.boost.org/more/lib_guide.htm#Guidelines

It may be that some compilers optimize the current code better than  
others and that some do very poorly. Also in accordance with the  
aforementioned guidelines we have not focused primarily on  
performance or performance testing. There is no fundamental reason  
why the code should not be able to be optimized away, but achieving  
that for many compilers may need to be left for later. It certainly  
will never happen without a putative starting point. Finally, if a  
nominally compile-time unit system incurs as much overhead as you  
seem to believe, imagine the cost of a runtime system...

Cheers,

Matthias
