Performance improvements

[polevaultweb]

The loading of the backend and frontend pages should be as fast as possible.

Not sure if this helps but there's a lot of potential here:

153 queries on the frontpage. Sure there has to be some but adding would certainly improve things.

@evrpress which page was that on?

[evrpress]

I get this on every page, logged in or not. I temporary use Query Monitor which reports about 50 duplicate queries in my case which mostly look like this:

SELECT meta_key AS key, meta_value AS value
FROM wp_postmeta
WHERE post_id = 444
AND ( meta_key LIKE "_link_roles|%" )
ORDER BY meta_key ASC

or

SELECT meta_key AS key, meta_value AS value
FROM wp_postmeta
WHERE post_id = 65
AND ( meta_key = "_link_visibility"
OR meta_key LIKE "_link_visibility|%" )
ORDER BY meta_key ASC

called by Carbon_Fields\Datastore\Meta_Datastore->get_storage_array()

I've noticed them because they are called twice. On a generic page (like this one) WP user manger does 164 SELECT queries, 153 only from the get_storage_array method.

Let me know if you need anything else

If you aren't using WPUM settings on menu items, you should be able to stop those queries with

define( 'WPUM_DISABLE_MENUS_CONTROLLER', true);

This basically solved it. I need the functionality though so this is not an option in production. Maybe you can add a caching layer to this until you get #270.
