WordPress 7.1.0PHP 8.4top 100

Heaviest single call

Ranked by the most Zend VM instructions one call can execute. This is how much work the function does itself, before it delegates: not a timing, and not a verdict on speed, since a single database call outweighs a thousand assignments.

Counted from the compiled opcodes, identical on any machine running the same PHP version. How this is measured.
