hi,
if you are talking about index fill factor:
The script will automatically reindex every index in every table of any database you select, and provide a fill factor of 90%. You can substitute any number appropriate for the fill factor in the above script.
So what is the ideal fill factor? It depends on the ratio of reads to writes that your application makes to your SQL Server tables. As a rule of thumb, follow these guidelines:
• Low Update Tables (100-1 read to write ratio): 100% fill factor
• High Update Tables (where writes exceed reads): 50%-70% fill factor
• Everything In-Between: 80%-90% fill factor.
