Performance profile

How much work a call to post_submit_meta_box() 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

246–377

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 760.

Plugin surface

3 hooks

Third-party callbacks on 'post_submitbox_minor_actions', 'post_submitbox_misc_actions', 'post_submitbox_start' run inside this call, and their cost is not bounded by anything here.

Called by

0

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

What it touches

• hookthird-party callbacksdo_action()called directly
• querycontent queryget_post()one call below post_submit_meta_box()
• optionoption read or writeget_option()one call below post_submit_meta_box()

Further down the call graph this can also reach 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 · 114 distinct outcomes

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

This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.
