Description

The replication process is operating too slowly to service demand resulting in lengthy delays to completion of replication tasks for new and changed content.

This is particularly apparent in the stage environment where perhaps the number of orphaned objects and deprecated / defunct nodes is interfering with expected behaviors.

Goal of this story is to identify and address the immediate issues. Any significant refactoring of the replication process should be captured under another story / epic.
