Performance profile

How much work a call to Twenty_Eleven_Ephemera_Widget::widget() 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
21–105

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 177.

Plugin surface
1 hook

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

0

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

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 · 9 distinct outcomes

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