Performance profile

How much work a call to wp_xmlrpc_server::wp_newComment() 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

Heavy

Reaches the database via get_post().

Scaling

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

23–152

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 273.

Plugin surface

4 hooks

Third-party callbacks on 'xmlrpc_allow_anonymous_comments', 'allow_empty_comment', '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.

What it touches

• optionoption read or writeget_option()called directly
• querycontent queryget_post()called directly
• cacheobject cachewp_cache_get()one call below wp_xmlrpc_server::wp_newComment()
• serializeserialisationmaybe_unserialize()one call below wp_xmlrpc_server::wp_newComment()

Further down the call graph this can also reach transient. That is the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 424 distinct outcomes

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

This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.

Hooks and filters fired · 4

4 hooks fire while wp_xmlrpc_server::wp_newComment() runs, in this order:

1. 1

   Filters whether an empty comment should be allowed.

3. 3
   do_action( xmlrpc_call )actionline 4032 (+115 into the body)

   Fires after the XML-RPC user has been authenticated but before the rest of the method logic begins.

4. 4
   do_action( xmlrpc_call_success_wp_newComment )actionline 4051 (+134 into the body)

   Fires after a new comment has been successfully created via XML-RPC.
