Let's say C++ can code be executed OVER 9000% faster than python.<p>However this does not imply a web app written in C++ will run even 1% faster than a web app written in python unless the performance bottleneck is code execution.<p>If the performance bottleneck is instead the database server (which it almost always is) then choosing C++ for your next webapp would be a _very_ masochistic premature optimization.
