Performance profile
How much work a call to wp_notify_moderator() 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.

The body loops, so the work grows with what you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 427.
Third-party callbacks on 'notify_moderator', 'comment_moderation_recipients', 'comment_moderation_headers' run inside this call, and their cost is not bounded by anything here.
1 place in core call this, so the cost is paid more often than your own code shows.
What it touches
- mailsends mail
wp_notify_moderator()this function does it - optionoption read or write
get_option()called directly - hookthird-party callbacks
apply_filters()called directly - querycontent query
get_post()called directly - sqldatabase query
->get_var()called directly - cacheobject cache
wp_cache_get()one call below wp_notify_moderator() - serializeserialisation
maybe_unserialize()one call below wp_notify_moderator()
Further down the call graph this can also reach transient. That is the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 7 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_notify_moderator() 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.
