Cost profile

Measured from the compiled opcodes, not from a stopwatch. Every number here is identical on any machine that runs the same PHP version, and every function in core is ranked by these figures.

Cost class
Trivial

Touches nothing outside its own arguments.

Scaling
Constant

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

Instructions
6

Executed per call on PHP 8.4. The body compiles to 6.

Plugin surface
None

Nothing here hands control to plugin code.

Called by
0

Nothing in core calls this; the cost is only what you spend yourself.

What one call costs · 1 distinct outcome

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

Oldest PHP that compiles this body: 7.4. An instruction is not a fixed amount of time, so a version with the same count is not necessarily the same speed; what the count rules out is a difference in the work itself.
