One other thing I though of when I was sending a moment ago, is the save
while active using *SYNCLIB or just *LIB? If it's *SYNCLIB that can be
unpredictable how long the synchronization can take.

Once a week, same time, we run a different job using the same control
group with different retention overrides and move policies.

The once a week *ALLUSR part of the save is consistently 10 to 15 minutes
faster than the daily save.
During the backup window, no batch jobs, only a handful of interactive
users.

Why would a retention override result in a performance improvement during
the *ALLUSR?
*ALLDLO and *LINK times are the same.
We do append, sequence numbers are higher for the nightly save compared to
the weekly save.

Thank You
