To be honest, I had to change the core::to_number lines (commented out) to boost::lexical_cast (right below the commented version), so the xpressive version could be slightly faster if I actually had the implementation of core::to_number available, and core::to_number was well made.
This could very well be the source of a major slow-down. Doesn't lexical_cast use string streams to do the conversion? It seems to me that you're comparing apples to oranges. Also, the warning you saw came from the user-created semantic action, not from xpressive. Robert, can you please post your complete code so that we can actually have meaningful numbers to look at?
