title: Optimal fill factor to prevent fragmentation
body: <p>Currently I use a daily job to <code>REORGANIZE</code> 1000+ indexes with > 5% and &lt; = 30% fragmentation and <code>REBUILD</code> indexes with > 30% fragmentation:

  <p>All indexes are rebuild with a fill factor of 80%, but based on my latest check, the fragmentation levels of 100+ indexes are unchanged. Most of them with a high fragmentation. I tried to play with the fill factor values in a test environment, but unfortunately can't simulate the production environment. </p>
  
  <p>I'm wondering if finding the 'best' fill-factor for each individual index is a good idea?</p>
