Performance profile

How much work a call to wp_get_recent_posts() 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_posts().

Scaling
Scales with input

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

Instructions
19–35

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 46.

Plugin surface
None

Nothing here hands control to plugin code.

Called by
4

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

What it touches

  • querycontent queryget_posts()called directly
  • hookthird-party callbacksdo_action()one call below wp_get_recent_posts()

Further down the call graph this can also reach option, cache, 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 · 2 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_get_recent_posts() 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.

Uses · 5

  • _deprecated_argument()Marks a function argument as deprecated and inform when it has been used.
  • __()Retrieves the translation of $text.
  • absint()Converts a value to non-negative integer.
  • wp_parse_args()Merges user defined arguments into defaults array.
  • get_posts()Retrieves an array of the latest posts, or posts matching the given criteria.
