Performance profile

How much work a call to _wp_auto_add_pages_to_menu() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Heavy

Reaches the database via get_posts().

Scaling

Scales with input

The body loops, so the work grows with what you pass in.
