Performance profile

How much work a call to getid3_matroska::playtimeFromMetadata() 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
Light

Touches nothing outside its own arguments.

Scaling
Scales with input

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

Instructions
5–26

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 29.

Plugin surface
None

Nothing here hands control to plugin code.

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

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.
