# Legacy options autoload

After import or migration, the original ACF option rows often remain in `wp_options`. They are no longer the canonical store but WordPress still loads any row with `autoload = on` on every request. That can add unnecessary weight to `alloptions` and slow down boot.

This plugin disables autoload on those legacy rows while it is active, and restores their previous autoload values when it is deactivated.
