When Device Level Sharing is not configured on a Centera partition and the sizes of the individual savesets in the staging area are of a generally large size, then the Enterprise Vault Collector threads may appear to process serially with large delays between the completion of one collection and the start of another. This results in a build up of savesets in the Staging area.
Dtrace of StorageFileWatch shows less than the default number of 100 items being added to the collection, and a large delay between the end of the first collection created by a thread and the start of the second collection by the same thread (In this example thread 4104 is shown):
10:17:40.914  (StorageFileWatch) <4104> EV:M CCollectorEMCCentera::CollectStore() - Lowest Saveset Identity = 11892794|Number of items to be collected 1|TransactionIds
10:17:48.464  (StorageFileWatch) <4104> EV:H CCollectorEMCCentera::CollectStore Time taken to process collection - VSDB Allocation: 0.015234, Store on Centera: 7.521709, Complete Collection: 0.010544 secs for CollectionID: 377924
10:21:26.320  (StorageFileWatch) <4104> EV:M CCollectorEMCCentera::CollectStore() - Lowest Saveset Identity = 11892837|Number of items to be collected 3|TransactionIds
10:21:27.895  (StorageFileWatch) <4104> EV:H CCollectorEMCCentera::CollectStore Time taken to process collection - VSDB Allocation: 0.016241, Store on Centera: 1.556359, Complete Collection: 0.008818 secs for CollectionID: 377939
