I think 2 of the suggestions helped me to get a better understanding of what needs to be done.
why rebuilding indexes? If doing this on schedule, maybe consider this first:

Dropping and recreating indexes won’t do that (and might make things worse, see tbone’s link); unless you’re talking about dropping, loading and then recreating. Gathering statistics will only help if the problem is that the existing statistics are stale or inaccurate and the explain plan(s) indicate it’s not working as expected. You need to explain what you’re doing and what problem you’re seeing – Alex Poole
