If you have lots of projectdoc documents then the in-memory properties cache might not perform optimal.
The projectdoc Toolbox caches document properties for quick access in memory and in the database. For the database caching we use Active Objects . For the in memory cache we use the Confluence Caching API.
As an admin user for Confluence you can watch and change the "projectdoc Document Cache" on the Cache Management page of the General configuration.
General Configuration
Click on the configuration wheel in the toolbar and choose "General configuration".
Entering Cache Statistics
Scroll down to and click on "Cache Management".
Now click on "Show advanced view"
Entering the Advanced View
Inspect the "projectdoc Document Cache" and determine a good cache size for your installation. For further Information on what the figures show see Cache Statistics.
Now click on "Adjust Size" of the "projectdoc Document Cache".
Adjusting the Size
Adjust the cache and submit the form.
