-            Smarty deliberately uses @filemtime() over file_exists() and filemtime() in some places. Reasons include
-                - @filemtime() is almost twice as fast as using an additional file_exists()
-                - between file_exists() and filemtime() a possible race condition is opened,
-                  which does not exist using the simple @filemtime() approach.
