The bug causes 500 Internal Server Errors for visitors on high volume sites during site startup.

Introduce an index that will help this highly utilized stored procedure that backs one of the provider calls to .GetChildren(). Adding this index will bring each of the branches down Logical IOs by 98+% on tblContent.

Steps to reproduce:

1. Create a Alloy site.
2. Configure a custom content provider (for example, an XML content provider).
3. Create a content item on the default content provider with ID XXX and publish it.
4. Create a content item on the custom content provider with the same ID XXX and publish it.
5. Create a content item that includes an XML html string property.
6. Add content link (XXX) and custom content link into XML html string property.
7. Publish the content item from step 6.

Expected result:

Publish should be done without an exceptions.

Actual result:

Publish throws exception (item already exist).

Import content to a site with keep identity.
You see lot of warnings like:

6. Go to admin view > Scheduled Jobs > Trim Content Versions.

Expected result:
As mentioned in the user guide, selecting "Disable deletion of content versions" disables the automatic deletion of versions caused by the "Maximum number of versions" field. However, "Maximum number of versions" will be ignored if "Disable deletion of content versions" box is selected.
