Performance profile

How much work a call to get_the_comments_navigation() 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

Moderate

Reads stored settings via get_option(), cached per request but not free on a cold cache.

Scaling

Constant

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

Instructions

7–69

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 69.

Plugin surface

None

Nothing here hands control to plugin code.

What it touches

• optionoption read or writeget_option()one call below get_the_comments_navigation()
• hookthird-party callbacksapply_filters()one call below get_the_comments_navigation()

Further down the call graph this can also reach cache, serialize, query 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 · 2 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost get_the_comments_navigation() can have, taken from its control-flow graph on PHP 8.5.
