Performance profile

How much work a call to get_blogaddress_by_domain() 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
Trivial

Touches nothing outside its own arguments.

Scaling
Constant

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

Instructions
16–30

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 35.

Plugin surface
None

Nothing here hands control to plugin code.

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

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

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

What one call costs · 1 distinct outcome

One number would be a lie: the work depends on which branch runs. These are every distinct cost get_blogaddress_by_domain() 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.
