Performance profile

How much work a call to get_bookmark() 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

Heavy

Reaches the database via ->get_row().

Scaling

Constant

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

Instructions

12–74

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 100.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

7

7 places in core call this, so the cost is paid more often than your own code shows.

What it touches

• cacheobject cachewp_cache_add()called directly
• querycontent querywp_get_object_terms()called directly
• sqldatabase query->get_row()called directly
• hookthird-party callbacksapply_filters()one call below get_bookmark()

Further down the call graph this can also reach option, 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 · 16 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost get_bookmark() can have, taken from its control-flow graph on PHP 8.5.
