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

Heavy

Reaches the database via WP_Query::query().

Scaling

Constant

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

Instructions

14

Executed per call on PHP 8.4. The body compiles to 14.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

1

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

What it touches

Further down the call graph this can also reach hook — that is the worst case, several calls deep and usually down an error path, not what a normal call pays.

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_Query::query() can have, taken from its control-flow graph on PHP 8.4.

Across PHP versions

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.
