Performance profile

How much work a call to WP_Upgrader::delete_temp_backup() 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

Light

Touches nothing outside its own arguments.

Scaling

Scales with input

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

Instructions

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 62.

Plugin surface

None

Nothing here hands control to plugin code.
