Performance profile
How much work a call to WP_Textdomain_Registry::get() 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.

Touches nothing outside its own arguments.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 19.
Third-party callbacks on 'lang_dir_for_domain' run inside this call, and their cost is not bounded by anything here.
Nothing in core calls this; the cost is only what you spend yourself.

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_Textdomain_Registry::get() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
!$locale | 14 | apply_filters() |
$locale | 19 | ->get_path_from_lang_dir(), apply_filters() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
| 8.6-dev | 18 | 14–18 | 1 | 1 fewer instruction than PHP 8.5 |
| 8.5 | 19 | 14–19 | 1 | |
| 8.4 | 19 | 14–19 | 1 | |
| 8.3 | 19 | 14–19 | 1 | |
| 8.2 | 19 | 14–19 | 1 | |
| 8.1 | 19 | 14–19 | 1 | |
| 7.4 | 19 | 14–19 | 1 |
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.
Hooks and filters fired · 1
One hook fires while WP_Textdomain_Registry::get() runs, in this order:
- apply_filters( lang_dir_for_domain )filterline 105 (+12 into the body)

Uses · 2
- apply_filters()Calls the callback functions that have been added to a filter hook.
- WP_Textdomain_Registry::get_path_from_lang_dir()Gets the path to the language directory for the current domain and locale.
