Performance profile

How much work a call to get_attachment_icon_src() 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
Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions
15–61

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 76.

Plugin surface
1 hook

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

Called by
1

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

What it touches

  • querycontent queryget_post()called directly
  • hookthird-party callbacksapply_filters()called directly
  • cacheobject cachewp_cache_get()one call below get_attachment_icon_src()

Further down the call graph this can also reach 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 · 8 distinct outcomes

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

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 76 instructions, 15–61 executed per call, 7 branches. The work does not change between versions.

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.

Hooks and filters fired · 1

One hook fires while get_attachment_icon_src() runs, in this order:
