What happens when the CLEANUP script is configured to run on all entities in the DB?

It slows down considerably
It replaces truncate statements with delete statements
It adds more entities into the DB
It truncates the Warehouse tables and finishes quickly (correct)

Why does adding entities into the DB cause the CLEANUP script to run drastically slower?

Because it causes the script to replace truncate statements with delete statements
Due to insufficient memory allocated to the Murex Warehouse
It has no impact on the speed of the cleanup script
Because it introduces new entities that need to be cleaned up (correct)

What could be a potential cause if the cleanup process is hanging or taking a long time to complete?

Not enough processing units
The addition of new entities into the DB
Locks on the PS_%_EGC tables
Insufficient resources like memory or CPU time (correct)
