SQL Server 2005 Waits and Queues

Leave a comment (0) Go to comments

There are two complimentary sources of performance information for SQL Server. Wait types are an invaluable clue in analyzing overall system performance from an application point of view. Wait types provide a view of system performance from a SQL thread standpoint while Performance Monitor provides a view of system performance from a resource standpoint.
Wait statistics should be corroborated or associated with resource counters in Performance Monitor. For example, a high SQL Server wait types signal the need for additional PERFMON investigation of underlying resources such as processor, IO subsystem, network and so on. Together, these associations or correlations of wait types to performance counters, and other related counter ratios provide a broad picture of application performance.
In come cases, the experienced performance expert must look beyond the symptom to find the root problem. Although not exhaustive, the correlated performance information, possible conclusions and actions, and interesting ratios and comparisons sections shed light on actual root problems, given the symptoms. The waits and queues methodology presented here, identify system bottlenecks and propose additional corroboration and conclusions, where appropriate.
In sum, the performance methodology of waits and queues draws on the available performance information that consists of waitstats, PERFMON counters, and correlated information, to provide a broad profile of application performance. It is an invaluable tool in pinpointing bottlenecks and fixing performance problems.
