C++03 vs C++11 : STL

Hi If I have a legacy code developed in time of C++03 , I can definitely switch to C++11. If I don't update code for any of the scenario and assume that it builds successfully without any error, does it improve any performance? I am confused as I read once that vector performance will be faster for C++11.. ? Is it true ? If yes, why so ?
