Purpose
The purpose of this article is to assist with the handling of query tuning issues. This article provides guidelines for dealing with tuning problems. It assumes that there really is a query tuning problem as opposed to some other issue that makes queries perform in a sub-optimal way. There are already plenty of articles on this topic. These will be referenced from this article where appropriate rather than trying to duplicate existing material. Obviously an article such as this cannot cover all possibilities but rather attempts to indicate what to look for.
