Return value

Performance profile

How much work a call to wp_get_global_styles_svg_filters() 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

Only touches the object cache, via wp_cache_get().

Scaling

Constant

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

Instructions

18–37

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 38.

Plugin surface

None

Nothing here hands control to plugin code.

• hookthird-party callbacksdo_action()one call below wp_get_global_styles_svg_filters()

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