Performance profile

How much work a call to _wp_privacy_send_erasure_fulfillment_notification() 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.

Sends mail via wp_mail().

Scaling

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

8–167
