Performance profile
How much work a call to WP_Comments_List_Table::single_row() 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.

Reaches the database via get_post().
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 76.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.
What it touches
- querycontent query
get_post()called directly - hookthird-party callbacks
apply_filters()one call below WP_Comments_List_Table::single_row()
Further down the call graph this can also reach option, cache, serialize and transient. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 8 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Comments_List_Table::single_row() can have, taken from its control-flow graph on PHP 8.5.

| 8.5 | 76 | 24–74 | 6 | |
| 8.4 | 76 | 24–74 | 6 | 3 fewer instructions than PHP 8.3 |
| 8.3 | 79 | 24–77 | 6 | |
| 8.2 | 79 | 24–77 | 6 | |
| 8.1 | 79 | 24–77 | 6 | 2 fewer instructions than PHP 7.4 |
| 7.4 | 81 | 24–79 | 6 |
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.
