Hello. I have a small index with <4% fragmentation and only 85 pages. This index is causing performance issues for end users. The scheduled DB maintenance doesn't reorganize or rebuild this index since it doesn't qualify for that based on the given
criteria. However when I manually rebuild it, the query that runs for over 40 secs runs below 1 sec. I have forced this index to rebuild specifically as part of the nightly maintenance, however users still experience slowness up until I manually rebuild it
again (online). I can schedule it at a granular level, but there must be something else going on that has the impact. This database is on SQL 2016 on premises with .NET app accessing it. Thanks.
