SQL Server内部在执行一些特定的操作时,会和硬盘做读写交互,这也会影响物理硬盘响应SQL Server的IO请求的性能,使查询进程处于PageIOLatch或WriteLog等待。 一,使用性能计数器(Performance counter)监控硬盘 IO 首先要了解操作系统的存储管理,硬盘在操作系统分为:物理硬盘(Physical Disk)和逻辑硬盘(Logical Disk)。Windows...

也就是经常等待自动更新的完成而不能很快给查询做出即时的执行计划,这个时候就有2种方法可以选了:一是设置一个维护窗口,让服务器在这一个窗口内更新统计信息,而自动更新统计信息这个开关就可以关闭了;二是开启is_auto_upadte_stats_async_on,这个选项是可以让统计信息的更新在晚点的时刻进行更新,而...
