首先Memory Pages/Sec是windows Server - Performance Counter中的一个。
描述是这样的:系统为了解决hard page faults每秒从硬盘读写的page数。
这个指标能表现出大部分系统延时(变慢)的主要原因(内存问题)。
而什么是hard page fault呢?
Hard page faults occur when the page is not located in physical memory or a memory-mapped file created by the process。http://blogs.technet.com/b/askperf/archive/2008/06/10/the-basics-of-page-faults.aspx
