Meanwhile these systems are all equipped with swap systems to expand their memory in order to increase the degree of parallel execution and workload at the cost of its performance to some extent .

而在这些操作系统中，几乎无一例外地都使用了 交换系统，以牺牲一定性能的代价来扩展 内存 空间 容量，增加系统的并行执行度和吞吐量。

Another performance issue for low-traffic websites is that GAE swaps inactive JVMs out of memory to optimize for high-traffic web applications on the system .

Now finally swap has the ability the power to modify memory that isn 't his own that 's not in his own scope because we 've passed it in by address .

最终 swap有能力，来修改不属于它的 内存，不在它的作用域中，因为我们是通过地址传递的。

Paging space or swap space is a type of logical volume that serves as a staging area for processes that are not using active random-access memory ( RAM ) .

分页空间（或 交换空间）是一种逻辑卷，用来存储不使用随机存取 存储器（RAM）进程的临时区域。

Ideally the memory manager can swap processes fast enough that some processes will be in memory ready to execute when the CPU scheduler wants to reschedule the CPU .

理论上，内存管理器能足够快速的 交换一些已在 内存中的过程，当调度器要重新规划CPU时，准备执行。

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。

A large swap space is also advisable for a system with very small memory .

建议为 内存极小的系统使用较大的 交换空间。

But the moment swap returns the moment we hit this bottom most curly brace what conceptually happens in memory ?

但是 swap返回时，当我们抵达花括号底端是，在 内存中发生了什么？

The command displays the total amount of free used physical and swap memory in the system as well as the buffers used by the kernel .

With it comes a set of constraints not seen in the desktop computer market in years : 128 to256 MB of RAM in-order CPUs that max out at1GHz and a complete lack of swap in the virtual memory system .

在台式机上多年不见得配置重新出现：128至256MB内存， 1GHz定序处理器，无虚拟 内存。

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。

The perceived heavier use of swap is balanced by the more efficient use of main memory .

这大量使用 交换 空间会因 内存使用的更加有效而得到平衡。

You 've also seen how you can permanently add swap to your configuration and how to add swap in an emergency when you run out of memory .
