I have noticed that several nodes exhibit long delays between when
backup of one filespace ends and the next one starts.
Here is an excerpt from one dsmsched.log file that illustrates the problem:

Note the time difference between when backup of '/' end and next
filespace starts!
Is this a known bug or a performance problem I'm having here?
If this is a performance problem, what are the initial steps should
be taken to address the issue?
