This post aims to aggregate a lot of the best practice or otherwise recommended configuration for SQL Server performance. It is meant as a summary or quick-reference sheet. All of these concepts are discussed at length all over the internet, so I will not spend much time explaining them.
As with any recommendations of this sort please use them carefully and test before deploying into a production environment. Also, depending on your specific environment's configuration, not all of the below may be advisable or bring about clear benefits. To quote Jonathan Kehayias: "While there is a lot of good guidance available for how to best configure SQL Server, the specifics of any given implementation is a very big “It Depends…”" What this post should achieve is providing the reader with an awareness of features and options that influence a SQL Server instance's operation.
