Reaches the database via WP_User_Search::query().
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4, depending on the branch taken. The body compiles to 44.
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.

Further down the call graph this can also reach hook, 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 · 2 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_User_Search::query() can have, taken from its control-flow graph on PHP 8.4.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 30 | ->get_col()__() |
| always | 34 | ->get_col()->get_var() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 44 | 30–34 | 1 | Compiles to the same instructions |
8.1 | 44 | 30–34 | 1 | Compiles to the same instructions |
8.2 | 44 | 30–34 | 1 | Compiles to the same instructions |
8.3 | 44 | 30–34 | 1 | Compiles to the same instructions |
8.4 | 44 | 30–34 | 1 | Compiles to the same instructions |
Oldest PHP that compiles this body: 7.4. An instruction is not a fixed amount of time, so a version with the same count is not necessarily the same speed; what the count rules out is a difference in the work itself.
