Performance profile

How much work a call to wp_ajax_add_meta() 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_post().

Scaling
Constant

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

Instructions
60–136

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 262.

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

  • querycontent queryget_post()called directly
  • hookthird-party callbacksdo_action()one call below wp_ajax_add_meta()
  • serializeserialisationmaybe_unserialize()one call below wp_ajax_add_meta()
  • cacheobject cachewp_cache_delete()one call below wp_ajax_add_meta()

Further down the call graph this can also reach option 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 · 95 distinct outcomes

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