根据SQL执行时长来优化
1)先清除缓存计划,注意生产环境谨慎使用此语句!dbccfreeProcCache2)再执行查询,系统使用等等3)查找执行最长的语句时间,可能需要执行多次来判断平均时间,代码如下:SELECTcreation_timeN‘语句编译时间‘,last_execution_timeN‘上次执行时间‘,total_physical_readsN‘物理读..

KVM硬件辅助虚拟化之 EPT(Extended Page Table)
传统OS环境中,CPU对内存的访问都必须通过MMU将虚拟地址VA转换为物理地址PA从而得到真正的Physical Memory Access,即:VA->MMU->PA,见下图。 虚拟运行环境中由于Guest OS所使用的物理地址空间并不是真正的物理内存,而是由VMM供其所使用一层虚拟的物理地址空间,为使MMU能够正确的转换虚实地址,Guest中的地址空间的转换和访问都必须借助VMM来实现,...
