Performance profile

How much work a call to get_block_editor_theme_styles() 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

Scales with input

The body loops, so the work grows with how much data it finds.

Instructions

4–11

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 51.

Plugin surface

None

Nothing here hands control to plugin code.

• hookthird-party callbacksapply_filters()one call below get_block_editor_theme_styles()

Further down the call graph this can also reach option, cache, serialize, transient and query. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

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 get_block_editor_theme_styles() can have, taken from its control-flow graph on PHP 8.5.
