The speed indicated for the restore is around 53MB/s versus 9.5 for the
backup. I would said the restore goes faster, but take more time.
Was other jobs scheduled or running when you run the restore ?
llist jobid={restorejobid}
list joblog jobid={restorejobid}
To detect if something block the job (like no access to storage daemon at that
time etc).
