Performance profile

How much work a call to ftp_base::mdel() 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 ->delete().

Scaling
Scales with input

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

Instructions
17–56

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 93.

Plugin surface
None

Nothing here hands control to plugin code.

1

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

What one call costs · 7 distinct outcomes

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