Performance profile

How much work a call to wp_admin_bar_appearance_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
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
13–102

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 103.

Plugin surface
None

Nothing here hands control to plugin code.

What it touches

  • hookthird-party callbacksapply_filters()one call below wp_admin_bar_appearance_menu()

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 · 50 distinct outcomes

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

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 103 instructions, 13–102 executed per call, 7 branches. The work does not change between versions.

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.
