Performance profile

How much work a call to wp_credits() 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

Expensive

Reaches an outbound HTTP request via wp_remote_get().

Scaling

Constant

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

Instructions

17–78

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 80.

Plugin surface

None

Nothing here hands control to plugin code.

What one call costs · 36 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_credits() can have, taken from its control-flow graph on PHP 8.5.
