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

Sends mail via wp_mail().
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 160.
Third-party callbacks on 'wpmu_signup_blog_notification', 'wpmu_signup_blog_notification_email', 'wpmu_signup_blog_notification_subject' run inside this call, and their cost is not bounded by anything here.
Nothing in core calls this; the cost is only what you spend yourself.
What it touches
- hookthird-party callbacks
apply_filters()called directly - optionnetwork option
get_site_option()called directly - querycontent query
get_user_by()called directly - mailsends mail
wp_mail()called directly - cacheobject cache
wp_cache_get()one call below wpmu_signup_blog_notification() - serializeserialisation
maybe_unserialize()one call below wpmu_signup_blog_notification()
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 · 49 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wpmu_signup_blog_notification() can have, taken from its control-flow graph on PHP 8.5.
