Performance profile

How much work a call to wp_insert_comment() 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 ->insert().

Scaling

Scales with input

The body loops, so the work grows with what you pass in.

Instructions

88–134

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 174.

Plugin surface

1 hook

Third-party callbacks on 'wp_insert_comment' run inside this call, and their cost is not bounded by anything here.

Called by

2

2 places in core call this, so the cost is paid more often than your own code shows.

What it touches

• cacheobject cachewp_cache_delete_multiple()called directly
• hookthird-party callbacksdo_action()called directly
• sqldatabase query->insert()called directly
• optionoption read or writeget_option()one call below wp_insert_comment()

Further down the call graph this can also reach serialize, query 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 · 6 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_insert_comment() 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 · 1

One hook fires while wp_insert_comment() runs, in this order:

1. 1
   do_action( wp_insert_comment )actionline 2091 (+78 into the body)

   Fires immediately after a comment is inserted into the database.

• current_time()Retrieves the current time based on specified type.
• get_gmt_from_date()Given a date in the timezone of the site, returns that date in UTC.
• wp_update_comment_count()Updates the comment count for post(s).
• wp_cache_delete_multiple()Deletes multiple values from the cache in one call.
• clean_comment_cache()Removes a comment from the object cache.
• get_comment()Retrieves comment data given a comment ID or comment object.
• add_comment_meta()Adds meta data field to a comment.
• do_action()Calls the callback functions that have been added to an action hook.
