SQL Server查询存储是一种性能监视工具,可以帮助我们根据几种不同的性能指标(例如,CPU和内存消耗,执行时间以及查询消耗的I / O周期)评估SQL查询的性能。 查询存储类似于窗口“任务管理器”。 任务管理器提供有关进程的CPU,内存,网络和磁盘消耗的信息。 同样,查询存储可提供对相似信息的洞察力。
that provide an overview of the performance of your SQL Server instance. It includes reports for CPU usage, disk I/O, memory usage, and other important performance metrics. These reports are generated using the dynamic management views (DMVs) and system catalog views provided by SQL Server. ...
