Performance profile
How much work a call to WP_Site_Health::enqueue_scripts() 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.

Reads stored settings via get_option(), cached per request but not free on a cold cache.
The body loops, so the work grows with how much data it finds.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 131.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.
What it touches
- transienttransient
get_transient()called directly - serializeserialisation
json_decode()called directly - hookthird-party callbacks
apply_filters()one call below WP_Site_Health::enqueue_scripts() - cacheobject cache
wp_cache_get()one call below WP_Site_Health::enqueue_scripts() - optionoption read or write

Further down the call graph this can also reach query. That is the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 5 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Site_Health::enqueue_scripts() can have, taken from its control-flow graph on PHP 8.5.

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.
