On: Using C++ as a scripting language, part 8

Maybe it is because of Debug vs. Release mode (and the optimization level coming with it) but I see a speed difference on the order of 10-100x vs. Release mode GCC

For heavily template code, a 10x-100x speed difference between -O0 and -O3 is not surprising in my experience.

The cost of compiling at -O3 is going to affect interactive use of course though.
