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。

In addition to the filesystem use covered so far, you also need to consider allocating swap space on disk.

除了上述的文件系统使用方法之外，您还需要考虑在磁盘上分配交换空间。

For a server, you might want to use a swap space of about half of your RAM, unless you are running an application that recommends a different value.

对于服务器来说，除非需要运行建议不同值的应用程序，否则您可能希望使用大小约为RAM一半的交换空间。

To add the swap space permanently to your system, you must configure one of the boot configuration files to enable the swap allocation automatically.

若要永久地将交换空间添加到系统，您必须配置启动配置文件之一来自动启用交换空间分配。

Note that swap space added in this way will not be retained during a reboot.

请注意，以这种方式添加的交换空间在重新启动后不会保留。

But there are several differences and nuances between RHEL4 swap space and AIX」s paging space.

但是，在RHEL4交换空间和AIX的分页空间之间有几点差异。

There are times when you can run out of configured swap space partitions and, for a short period, require more VM until you can organize a more permanent solution.

有时您可能会用尽已配置的交换空间分区，从而在短时间内需要更多VM，直到您能够组织某种更永久性的解决方案。

Choosing the right amount of swap space is highly dependent on the platform you are configuring — it「s intended use and how you want to cope with a lack of available VM.

选择正确的交换空间量很大程度上取决于您所配置的平台——其预期用途和您希望如何处理可用VM缺乏的情况。

A once common rule of thumb was to create swap space equivalent to the amount of real RAM.

一种常见的经验法则是创建与实际RAM大小相同的交换空间。

Low free list values might indicate that you have a lot of active RAM in use, which might trigger swap space use if you add more processes to the system.

较低的空閑列表值可能表示使用了大量的活动RAM，如果您向该系统中添加更多的进程，那么可能引起交换空间的使用。

You should configure a dedicated partition for swap space as soon as possible.

您应该尽快为交换空间配置专用分区。

For example, let」s say that one area of memory is currently in swap space while another one is in memory.

例如，假设一个内存区当前在交换空间中，而另一个在内存中。

Releasing space allows the underlying operating system to cut down on swap space requirements and reuse memory mapping tables.

释放空间使底层操作系统减小对交换空间的许求并且重用内存映射表。

For performance reasons or when diagnosing a problem that you suspect might be swap space related, you often need a more interactive view of the memory and paging usage.

出于性能的考虑，或者在诊断您怀疑可能与交换空间有关的问题时，您通常需要内存和分页使用情况的更加交互式的视图。

Part 3 focuses specifically on swap space and how best to tune your VMM Settings to provide for optimum swap space configuration and performance.

第3部分主要介绍交换空间，以及如何最好地优化VMM设置，以提供最优的交换空间配置和性能。

On a desktop system, allocate at least as much swap space as physical RAM.

在桌面系统上，至少分配与物理ram一样多的交换空间。

The amount of swap space that you configure on your machine is largely dependent on the application and operating system.

您在计算机上配置的交换空间量主要取决于应用程序和操作系统。
