How is std::string implemented? http://stackoverflow.com/questions/1466073/how-is-stdstring-implemented copy on write when a string object is copied unchanged the refcount is incremented but the actual string data is not. Both object.. actual string data is not. Both object point to the same refcounted data until one of the objects modifies it causing a 'copy.. of the data. The variations are in where things like the refcount locks etc are stored. a short string optimization SSO implementation...

Should I switch from using boost::shared_ptr to std::shared_ptr? http://stackoverflow.com/questions/6322245/should-i-switch-from-using-boostshared-ptr-to-stdshared-ptr to be move semantics enabled which might save a few refcount modifications. Theoretically I've not tested this myself Debuggers...
