How to optimize tree-loading of the site-admin

Symptoms

Loading of page hierarchies in the site-admin tree navigation takes a long time.

Cause

The tree in the site-admin preloads an additional hierarchy level when expanding the tree for a given root. This can cause performance issues if a lot of pages have to be loaded.

Example

Following structure is given:

• /content/mysite/en
• /content/mysite/de
• /content/mysite/fr
• /content/mysite/it

Every country site has 20 direct child-pages, so expanding /content/mysite would result in loading 80 pages.

Resolution

It is possible to disable the preloading in the site-admin to improve performance. Please configure the following:

• via the CRX Content Explorer, navigate to the node /libs/wcm/content/siteadmin
• add a boolean property labeled considerSubNodes and set it to false
• save

Now everytime a tree is expanded in the site-admin, only the direct children will be fetched.

NOTE: changing something beneath /libs is usually discouraged as it breaks potential updates in the future. In this case, a mere modification of content is regarded harmless.
