Hi Gerhard,

in my opinion the easiest way to check the amount of time for an auditdb is
to perform online an audit db with preview=yes(default).
This will last nearly the same (without time used for fixing) as the
offline audit.

Also this will show you, whther the audit is really needed.

If there's something to fix I'd suggest to do the fixes online cause you
don't know what will happen to your db otherwise.
