/SM590000Document: With this expiration type, a document at a time is deleted from the application 
group. Data that is stored in archive storage is deleted by the storage manager based on 
the archive expiration date. Storing documents with an expiration type of Document 
causes the expiration process to search through every document in the segment to 
determine whether the expiration date was reached, which results in long processing 
times. 
When the arsmaint expiration process is run, data is deleted only from the application group if 
the upper threshold for the size of the cache storage is reached. By default, the cache 
threshold is 80%. A lower threshold can be forced by the expiration command parameters. 
Unless a reason exists to clear cache, leaving data in cache improves retrieval performance. 
5.2.6  Advanced application group storage management
By using the advanced storage management settings (Figure 5-11), you can adjust the size of 
the load object and determine when report data, indexes, and resources are migrated to 
archive storage.

Object Size
The Object Size parameter determines the size of a storage object in kilobytes (KB). Content 
Manager OnDemand, by default, segments and compresses stored data into 10 MB storage 
objects. The default of 10 MB is the most commonly used object size value. 
Important: Be careful when you change the value for Object Size. Setting the value too 
small or too large can adversely affect load performance. However, increasing this value 
might be necessary if you load large files and run out of Object IDs during the loading 
process.
Note: The object size that is defined here must be equal to or larger than the size of the 
compressed storage objects that are defined in any application that is assigned to the 
application group.
