Performance profile
How much work a call to upgrade_560() 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_var().
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 61.
Nothing here hands control to plugin code.
1 place in core call this, so the cost is paid more often than your own code shows.
What it touches
- optionoption read or write
update_option()called directly - transienttransient
delete_transient()called directly - sqldatabase query
->get_var()called directly - hookthird-party callbacks
apply_filters()one call below upgrade_560() - serializeserialisation
maybe_serialize()one call below upgrade_560() - cacheobject cache
wp_cache_get()one call below upgrade_560()
Further down the call graph this can also reach query. That is the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 36 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost upgrade_560() can have, taken from its control-flow graph on PHP 8.5.

Across PHP versions
Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 61 instructions, 11–61 executed per call, 6 branches. The work does not change between versions.
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.
