Performance profile

How much work a call to wp_get_available_translations() 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
Expensive

Reaches an outbound HTTP request via wp_remote_post().

Scaling
Scales with input

The body loops, so the work grows with how much data it finds.

Instructions
10–38

Executed per call on PHP 8.4, depending on the branch taken. The body compiles to 44.

Plugin surface
None

Nothing here hands control to plugin code.

2

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

Further down the call graph this can also reach serialize and query. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 5 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_get_available_translations() can have, taken from its control-flow graph on PHP 8.4.

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3 and 8.4: 44 instructions, 10–38 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.
