Performance profile

How much work a call to wp_list_bookmarks() 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_terms().

Scaling
Scales with input

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

Instructions
60–118

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 174.

Plugin surface
2 hooks

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

Called by
3

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

What it touches

  • querycontent queryget_terms()called directly
  • hookthird-party callbacksapply_filters()called directly
  • cacheobject cachewp_cache_get()one call below wp_list_bookmarks()
  • optionoption read or writeget_option()one call below wp_list_bookmarks()

Further down the call graph this can also reach 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 · 12 distinct outcomes

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