Performance profile
How much work a call to wp_xmlrpc_server::pingback_extensions_getPingbacks() 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_results().
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 67.
Third-party callbacks on 'xmlrpc_call' 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.

get_option()one call below wp_xmlrpc_server::pingback_extensions_getPingbacks()
Further down the call graph this can also reach 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 · 3 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_xmlrpc_server::pingback_extensions_getPingbacks() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 26 | do_action(), ->escape(), url_to_postid(), __(), ->pingback_error() |
| always | 33 | do_action(), ->escape(), url_to_postid(), get_post(), __(), ->pingback_error() |
| always | 39–43 | do_action(), ->escape(), url_to_postid(), get_post(), ->prepare(), ->get_results() |
Across PHP versions
Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 67 instructions, 26–43 executed per call, 6 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.
Hooks and filters fired · 1
One hook fires while wp_xmlrpc_server::pingback_extensions_getPingbacks() runs, in this order:
- do_action( xmlrpc_call )actionline 7208 (+4 into the body)
Fires after the XML-RPC user has been authenticated but before the rest of the method logic begins.
Uses · 6
- do_action()Calls the callback functions that have been added to an action hook.
- url_to_postid()Examines a URL and try to determine the post ID it represents.
- __()Retrieves the translation of $text.
- get_post()Retrieves post data given a post ID or post object.
- wp_xmlrpc_server::escape()Escapes string or array of strings for database.
- wp_xmlrpc_server::pingback_error()Sends a pingback error based on the given error code and message.
