std::map actually does more than NSDictionary—it sorts its entries

it would be a much fairer test if you used std::string* pointers for
your keys and values instead of std::string objects, but it'd also
be a little more work since you'd need a custom comparator and you'd
need to consider memory management (which boost smart pointers
apparently can manage pretty well).
No need to pull in the whole boost overhead for smart(er) pointers as
of gcc 4.0.
#include <tr1/memory>
using std::tr1::shared_ptr;
And for the presorting time - TR1 includes also an unordered_map and
unordered_set.
