Hyperion Calculation Manager Performance Issue - Expanding Planning/Essbase node takes 5 Minutes

While attempting to Expand the Planing/Essbase node in Calculation Manager,  the user is observing it takes more than 5 minutes to display the contents.

STEPS
-----------------------
1. Login to calculation manager 
2. Expand the Planning/Essbase Tree (node)
3. Takes close to 5 minutes for the Tree to expand and display the contents

In order to resolve this, try this out on the server where Calc Manager is installed:

• Verify that the Dimension service is started and is up and running
• Start the Dimension server service if it is in the shut-down status
• Wait 2-3 minutes for the service to become stable
• Try to login into Calc Manager and expand the node
