Performance profile

How much work a call to WP_Widget_Media::update() 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 WP_Widget_Media::update().

Scaling

Scales with input

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

Instructions

8–9

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 50.

Plugin surface

None

Nothing here hands control to plugin code.

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

What it touches

• sqldatabase queryWP_Widget_Media::update()this function does it
• hookthird-party callbacksdo_action()one call below WP_Widget_Media::update()

Further down the call graph this can also reach option, cache, 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 · 1 distinct outcome

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