IIS7.5管理器中的“虚拟字节”在“工作进程”窗格中的含义是什么?
如果我打开IIS管理器(在WindowsServer 2008r2上),并转到工作进程页面,我可以看到我的一个AppPool进程报告
Private Bytes (KB) 106,435.00
Virtual Bytes (KB) 748,788.00
但是,如果我查看任务管理器,关联的w3wp.exe进程报告69,276K.
谁能向我解释这些数字是如何相互关联的?
谢谢
以下文章应该有助于解释:

任务管理器中显示的内存是进程使用的物理内存量,无法与其他进程共享.
以下内容应该有助于解释虚拟地址空间:

TechNet和MSDN中的定义:
Private Bytes (KB). The current size of memory committed to a worker process,which cannot be shared with other processes. This corresponds to Virtual Memory Size in Windows Task Manager.
Virtual Bytes (KB). The current size of the virtual address space for a worker process. This does not correspond to anything in Windows Task Manager.
Virtual Address Space: A virtual address does not represent the actual physical location of an object in memory; instead,the system maintains a page table for each process,which is an internal data structure used to translate virtual addresses into their corresponding physical addresses. Each time a thread references an address,the system translates the virtual address to a physical address.
