fill factor Option
This option sets the server-wide default fill-factor value. Fill factor is provided for fine-tuning index data storage and performance. When an index is created or rebuilt, the fill-factor value determines the percentage of space on each leaf-level page to be filled with data, reserving the rest as free space for future growth. For more information, see Fill Factor.
The following example shows how to use sp_configureto set the fill factor server configuration option to 100. Using sp_configure, you can change fill factor only when show advanced options is set to 1. The setting takes effect after restarting the server. For more information, see Setting Server Configuration Options.
