DD4500 Data Movement to archive tier uses all the resources

We have setup a DD4500 for our cloud.  Recently, we see backup running extremely slow with lots of timeout error on NetWorker.  Reboot the backup server, reset jobsdb and tmp do not fix the issue.
Suspect it is something similar to "Cleaning Affects Ingest in 5.2. User Cannot Throttle Down  kb182136".  So contact support and turn out it is the Data movement to a archive tier taking all the resource.

We attempt to change the throttle for Data Movement with help of support but it does not seem to help.  Only option is to upgrade to DDOS 5.4.3.0 or Disable Data Movement.  We suspend the Data movement as a workaround.  Then the backup speed is back to normal.

We finally complete the update of DDOS to DDOS 5.4.3.0, and we no longer see the issue again.
