High efficiency of program execution in compiled languages

Compiled language written by the program before the execution, need a special compilation process, the program compiled into machine language files, such as EXE files, later to run without re-translation, directly using the results of the compilation (EXE file), because the translation is done only once, the runtime does not need to translate, Therefore, the program execution efficiency of the compiled language is high.
