Performance profile
How much work a call to wp_save_nav_menu_items() 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.

Reaches the database via get_term().
The body loops, so the work grows with what you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 131.
Nothing here hands control to plugin code.
1 place in core call this, so the cost is paid more often than your own code shows.
What it touches
- querycontent query
get_term()one call below wp_save_nav_menu_items() - hookthird-party callbacks
do_action()one call below wp_save_nav_menu_items()
Further down the call graph this can also reach 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 · 1 distinct outcome
One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_save_nav_menu_items() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
$menu_id === 0 | 11–12 | none |
This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
| 8.6-dev | 131 | 11–12 | 26 | |
| 8.5 | 131 | 11–12 | 26 | |
| 8.4 | 131 | 11–12 | 26 | |
| 8.3 | 131 | 11–12 | 26 | |
| 8.2 | 131 | 11–12 | 26 | |
| 8.1 | 131 | 11–12 | 26 | 13 fewer instructions than PHP 7.4 |
| 7.4 | 144 | 11–12 | 26 |
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.
