Runtime optimized/non-optimized

[Nils H. Busch]

Hello,

I have a general question, I could not exactly answer myself.

Why is the runtime of Pooma code so much longer when running in debug
mode (-g) compared to optimized code (-Ox), order of magnitude at least
10x? This concerns both apps compiled in both ways as also the library
itself.
Even for parts that are not Pooma related, there is a great runtime
difference.
I suspect, it has to do with the template expression mechanism, but I
would like to understand exactly what the compiler does so differently.

Thanks.
