Review comment:
Output Op duration is the time taken for all the jobs of that batch to
finish processing from the time they were submitted. So it gives scheduling
delay(time to schedule first job of the batch) + processing delay(time from
start of processing of first job till the end of processing of last job of
batch).
While job duration gives detail about a single job, Output Op duration gives
info about the entire batch.
