Improve the speed of opening a map

To improve the speed at which the IXIA CCMS Desktop opens a map, you can configure objects so that they do not automatically load when a user opens a map.

For example, you could configure the CCMS Desktop so that submaps do not automatically load when a user opens a map. The submaps only load once the user opens them from the DITA Map view.

Important: Make configuration changes in a test environment and confirm they work before copying them to a production environment.

To improve the speed of opening a map:

In the TEXTML Administration perspective, connect to your server.
Locate the display.xml file in the repository's /system/conf collection.
Check out the file and open it for editing.

Locate the <maps> element.

For example:

...
<maps>
   <references>
      <unexpanded class="- map/map container/container "/>
      <unexpanded class="- map/map container/container containerpart/containerpart "/>
   </references>
   <container class="- map/map container/container ">
      <subcontainer xpath="//*[contains(@class, ' mapgroup-d/mapref ')]" attrib="href"/>
   </container>
</maps>

By default, the DITA Map view does not load the containers, which are used in the Dynamic Release Management (DRM) module.

To configure an object so that it does not get loaded, add its class to the <references> element.
For example, to prevent submaps from being loaded when you open a map, add the map class to the <references> element, as follows:
```
...
<references>
   <unexpanded class="- map/map "/>
```
Save, close, and check in the file.
Inform users of the changes.
The changes are automatically applied once users close and then reopen their IXIA CCMS Desktop. Users can also apply the changes without restarting their CCMS Desktop by clicking IXIA CCMS > Synchronize Configuration.

The speed of opening a map is improved.
