VMM is a program on a host system that lets one computer support multiple, identical execution environments.
VMM是主机系统上的一个程序,它让一台计算机支持多个相同的执行环境。
Part 3 focuses primarily on swap space and other methods to tune your VMM to maximize performance.
第3部分重点关注分页空间和对VMM进行调优以尽可能提高性能的其他方法。
After the data file is copied into RAM, VMM controls when these pages are overwritten or used to store other data.
在将数据文件复制到RAM中之后,VMM控制何时对这些页面进行覆盖或者将其用于存储其他数据。
At the same time, VMM maintains a free list of unallocated page frames, which are used to satisfy page faults.
同时,VMM维护了一个未分配页帧的空閑列表,可以使用该列表来处理缺页的问题。
To reiterate, the purpose of VMM is to manage the allocation of both RAM and virtual pages.
要重申的是,VMM的目的是管理RAM和虚拟页面的分配。
What VMM also does is classify virtual memory segments into two distinct categories.
VMM还将虚拟内存段划分为两个不同的类别。
When a program accesses two pages of a file, VMM assumes that the program keeps trying to access the file in a sequential method.
当程序访问一个文件的两个页面时,VMM假定该程序将采用顺序的方法不断地尝试访问该文件。
In cloud computing, VMM allows users to monitor and thus manage aspects of the process such as data access, data storage, encryption, addressing, topology, and workload movement.
在云计算中,VMM允许监视用户,因此可以管理数据访问、数据存储、加密、寻址、拓扑和工作负载转移等方面。
Tuning the AIX VMM can result in significant performance improvements for workloads.
对AIXVMM进行优化,可以使得各种工作负载获得明显的性能改善。
When you first open a file, the AIX kernel creates an internal VMM object to represent the file.
当您第一次打开一个文件的时候,AIX内核将创建一个内部VMM对象以代表该文件。
VMM also maintains what is referred to as a free list, which is defined as unallocated page frames.
VMM还维护一个称为空閑列表的对象,该对象定义为未分配的页帧。
The article discussed best practices for disk configuration and VMM tuning in an NFS environment.
本文还介绍了在NFS环境中进行磁盘配置和VMM优化的最佳实践。
This article discusses in detail the AIX VMM and the tuning commands that you will be using to tune memory.
本文将详细讨论AIXVMM,以及将用于优化内存的各种优化命令。
It「s important to understand that the VMM services all memory requests from the system, not just virtual memory.
VMM为系统中所有的内存请求(而不仅仅是虚拟内存的内存请求)提供服务,了解这一点是非常重要的。
The AIX VMM integrates cached file data with the management of other types of virtual memory (for example, process data, process stack, and so forth).
AIXVMM将缓存的文件数据与对其它类型虚拟内存(例如,进程数据、进程堆栈等等)的管理集成到了一起。
VMM uses swap space (paging) as a holding bin for a process that is not using active RAM.
VMM使用交换(分页)空间存储没有使用活动RAM的进程。
Let」s examine the tools that can allow you to tune the VMM to optimize performance for your system.
让我们研究一些相关的工具,它们允许您对VMM进行优化,从而实现系统性能的优化。
Another important change includes VMM dynamic variable page size support (VPSS).
另一项重要的更改包括VMM动态可变页面大小支持(VPSS)。
Parts 1 and 2 of this series went over the VMM in great detail and covered troubleshooting memory bottlenecks.
本系列的第1部分和第2部分详细地介绍了VMM以及如何对内存瓶颈进行故障排除。
