Probably I'm making an obvious mistake and comparing entirely different things. These numbers seem a little strange. (average of 10, code attached) 19653.2ms extended for, range 12951.5ms foreach, range 83364.1ms extended for, int[] 66637.5ms foreach, int[] 11343.7ms while, int[] 22995.3ms extended for, ArrayList<int> 15753.1ms foreach, ArrayList<int> 17650.0ms while, ArrayList<int> 309.4ms empty while loop The extended for statement is very convenient - why the performance penalty compared to foreach? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112788&aid=875682&group_id=12788 ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
