Performance profile

How much work a call to Twenty_Fourteen_Ephemera_Widget::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.

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

An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
