Performance profile

How much work a call to render_block_core_media_text() 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

Scales with input

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

Instructions

6–155

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 176.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

0

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

• hookthird-party callbacksapply_filters()one call below render_block_core_media_text()
• querycontent queryget_post()one call below render_block_core_media_text()

Further down the call graph this can also reach cache, serialize, option 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 · 67 distinct outcomes

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