Performance profile

How much work a call to WP_Recovery_Mode_Email_Service::get_plugin() 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
Moderate

Only touches the object cache, via wp_cache_get().

Scaling
Scales with input

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

Instructions
19–31

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 41.

Plugin surface
None

Nothing here hands control to plugin code.

Called by
2

2 places in core call this, so the cost is paid more often than your own code shows.

What it touches

  • cacheobject cachewp_cache_get()one call below WP_Recovery_Mode_Email_Service::get_plugin()

Further down the call graph this can also reach hook, query, option, serialize 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_Recovery_Mode_Email_Service::get_plugin() 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.
