Performance profile

How much work a call to WP_Customize_Manager::save_changeset_post() 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

200–254

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 632.

Plugin surface

2 hooks

Third-party callbacks on 'customize_save_validation_before', 'customize_changeset_save_data' 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

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 · 116 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Customize_Manager::save_changeset_post() 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 · 2

2 hooks fire while WP_Customize_Manager::save_changeset_post() runs, in this order:

1. 1
   do_action( customize_save_validation_before )actionline 2780 (+140 into the body)

   Fires before save validation happens.

2. 2
