Creating a Baseline, a number of Performance Monitor metrics for gathering data on these parts of the system. Within the descriptions of most of the counters, I referred to comparing your metric to a baseline. This chapter will cover how to gather your metrics so that you have that baseline for later comparison. I’ll g

Index Architecture and Behavior, columns, can be the basis for all performance problems starting with basic data access, continuing through joins, and ending in filtering clauses. For these reasons, it is extremely important for everyone—not just a DBA—to understand the different indexing techniques that can be used to optimize th

Key Lookups and Solutions,ith nonclustered indexes is the cost of excessive lookups, formerly known as ., which are a mechanism to navigate from a nonclustered index row to the corresponding data row in the clustered index or the heap. Therefore, it makes sense to look at the cause of lookups and to evaluate how to avoid thi

Statistics, Data Distribution, and Cardinality,oing to access data. It also takes advantage of enforced referential constraint and other table structures. Finally, and possibly most important, the optimizer must have information about the data that defines an index or a column. That information is referred to as a .. Statistics define both the d
