11、Lock Pages in Memory Usage (KB) 含义:如果启用了“锁页”选项,则该值表示用于锁定到物理内存中的页数量(以千字节为单位)。 重要性:启用“锁页”可以防止SQL Server的工作集被换出到磁盘,提高性能。但是,这也减少了操作系统可用于其他进程的物理内存。 12、Large Pages Allocated (KB) 含义

Total Server Memory:自己分配的Buffer pool 内存总和。 Target Server Memory:理论上能够使用的最多内存数目。 SQL Server 内存使用量陡然下降现象: 原因: 1、windows在某种情况下申请了太多内核态内存,反而压缩了用户态可以使用的物理内存。 2、有些硬件驱动程序申请了太多内核态内存,也占用太多物理内存。
Total Server Memory:SQL Server自己分的代码申请的Buffer Pool空间大小,所有的Database Cache和大部分的Consumer(Connection、Query Plan、 Optimizer等)都保存在Buffer Pool中,对于一些特别长的语句的Query Plan、Optimizer等内存使用一部分的Multi-Page Buffer Pool = Max Server Memory 或 SQL physical memory-Multi-...
