Performance profile

How much work a call to WP_REST_Themes_Controller::get_item_schema() 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 how much data it finds.

Instructions
8–249

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 270.

Plugin surface
None

Nothing here hands control to plugin code.

0

Nothing in core calls this; the cost is only what you spend yourself.

What one call costs · 2 distinct outcomes

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

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 270 instructions, 8–249 executed per call, 4 branches. The work does not change between versions.

An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
