While looking at performance in some of my databases, I noticed there was a high number of FreeSpace scans going on. Aaargh! They are called clustered indexes, people use them! Performance, performance, performance!
In most cases it is best practices to start with a clustered index on every table created. There are rare instances when this is not the optimal setup, but for the large majority of standard databases put in a clustered index on each table. Your shooting yourself in the foot, people!
