Performance profile

How much work a call to WP_Site_Health_Auto_Updates::test_check_wp_filesystem_method() 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
Trivial

Touches nothing outside its own arguments.

Scaling
Constant

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

Instructions
20–29

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 35.

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 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_Site_Health_Auto_Updates::test_check_wp_filesystem_method() can have, taken from its control-flow graph on PHP 8.5.

WhenInstructionsCalls it makes
always20–23function_exists(), ->request_filesystem_credentials(), __()
always26–29function_exists(), ->request_filesystem_credentials(), __(), __()

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 35 instructions, 20–29 executed per call, 2 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.
