Comment (by Rarst):

 Replying to [comment:28 nacin]:
 > If we're going to make a function slower, it should be apply_filters()
 and do_action(). The functions add_filter() and add_action() get called
 thousands of times and need to be as fast as possible.

 `apply_filters()` is used in translate for `gettext` and routinely adds up
 to hundreds/thousands calls.

 At current point personally I wouldn't think of ''any'' performance
 degradation to these as acceptable. It's a glue that holds everything
 together and due to core (over)use is hard to manage for performance.
