Enable TF1117 & TF1118

TF1117 - When a file in the filegroup meets the autogrow threshold, all files in the filegroup grow. This behaviour will be enabled for all databases, not just tempdb.

TF1118 - Reduces contention on the SGAM page as new by allocating all eight pages from the same extent when creating new objects, minimizing the need to scan the SGAM page.

Suggested Action

Enable TF1117 & TF1118 on starup using startup parameters.
