Performance profile

How much work a call to wp_admin_bar_edit_menu() 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

14–110

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 307.

Plugin surface

None

Nothing here hands control to plugin code.

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

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 · 118 distinct outcomes

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