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.

Touches nothing outside its own arguments.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4, depending on the branch taken. The body compiles to 11.
Third-party callbacks on 'comment_loop_start' run inside this call, and their cost is not bounded by anything here.
Nothing in core calls this; the cost is only what you spend yourself.

What one call costs · 2 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Query::the_comment() can have, taken from its control-flow graph on PHP 8.4.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 8 | ->next_comment() |
| always | 11 | ->next_comment()do_action() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 11 | 8–11 | 1 | Compiles to the same instructions |
8.1 | 11 | 8–11 | 1 | Compiles to the same instructions |
8.2 | 11 | 8–11 | 1 | Compiles to the same instructions |
8.3 | 11 | 8–11 | 1 | Compiles to the same instructions |
8.4 | 11 | 8–11 | 1 | Compiles to the same instructions |
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.
