c++ Programming Glossary: sprintfVery poor boost::lexical_cast performance http://stackoverflow.com/questions/1250795/very-poor-boostlexical-cast-performance are in essence using the Java and Python equivalents of sprintf or the less standard itoa . In C you are using a very powerful.. sense of raw speed performance if you want speed perhaps sprintf would be better suited but powerful in the sense of extensibility... method then you should compare it with either C sprintf or C ostream facilities. The C stream solution would be 6 times..

C++ performance challenge: integer to std::string conversion http://stackoverflow.com/questions/4351371/c-performance-challenge-integer-to-stdstring-conversion against The C way using stringstream http ideone.com jh3Sa sprintf which SO ers usually recommend to the performance conscious.. . I believe that the code for my algorithm I know the sprintf benchmark takes some shortcuts now fixed is well defined behavior.. value helped only on gcc. Code was found that outperforms sprintf by an order of magnitude. ostringstream falls behind by a factor..
