install_dashboard()

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Performance profile

How much work a call to install_dashboard() 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

Heavy

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

Scaling

Scales with input

The body loops, so the work grows with how much data it finds.

Instructions

25–39

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 74.

Plugin surface

None

Nothing here hands control to plugin code.

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

• transienttransientget_site_transient()one call below install_dashboard()
• hookthird-party callbacksdo_action()one call below install_dashboard()

Further down the call graph this can also reach cache, option, http, query and serialize. 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 install_dashboard() can have, taken from its control-flow graph on PHP 8.5.

About this page

Parsed data

Generated from the wordpress-develop 6.7.7 tag, from src/wp-admin/includes/plugin-install.php, and regenerated for each WordPress release so it tracks the code rather than a snapshot of it.
