Every WordPress page load pulls in your autoloaded options in one go. Over time plugins pile data into that bundle, and a lot of it does not need to load on every request. When it grows into the megabytes, every page pays for it.

AutoLoad Forge gives you a plain Tools screen to see the problem and act on it:

A running total of how much data autoloads, and how many options make it up.
The biggest autoloaded options, largest first.
A best-effort guess at which plugin each option belongs to, so you know what you are looking at.
A one-click switch to stop an option autoloading, and a list of everything you have switched off so you can turn any of it back on.

It does not delete anything. Turning autoload off leaves the option in place and fully intact, it just stops loading on every request. If something turns out to need it, restore it in one click.

No settings to configure, no external calls, no tracking. Open the page, read it, decide.
