On the other hand, message buffering can be expensive, as it entails additional memory-to-memory copying, and it requires the allocation of memory for buffering.
另一方面，消息缓冲可能是代价高昂的，因为它需要额外的“内存到内存”的拷贝操作，同时它还需要申请用于缓冲的存储区。

To reduce memory usage, start by identifying the largest consumers of memory.
为了减少内存消耗，先要找出内存的消耗大户。
Before assigning extra paging space to your system, it's worth looking at memory allocation and memory tuning.
为系统分配额外的分页空间之前，检查内存分配和内存调优是值得的。
For example, if more memory is needed for sort operations and some buffer pools have excess memory, the memory tuner frees up the excess buffer pool memory and allocates it to the sort heaps.
例如，如果排序操作需要更多的内存，而一些缓冲池又有多余的内存，那么内存调优器会释放多余的缓冲池内存，并将它分配给排序堆。
The more senses you involve when you need to encode memory, usually the more strong a memory it becomes.
在你需要为记忆编码时，感觉越多，通常记忆也越强。
You can develop an algorithm that USES little memory for management but takes more time to manage the available memory.

Finally, having extra memory on hand allows the file systems to cache files and metadata in memory.
最后，安装更多内存让文件系统可以把文件和元数据缓存在内存中。
Obviously, administrators prefer to use physical memory rather than paging space, where the physical memory is available.
很显然，在可以使用物理内存的情况下，管理员更希望使用物理内存，而不是分页空间。
The SPE cannot read main memory directly, but instead must import and export data between the local store and main memory using DMA commands to a unit called the memory flow controller, or MFC.
SPE不能直接读取主存，相反地必须通过对内存流控制器(或mfc)的单元使用dma命令来在本地存储和主存之间导入和导出数据。
Memory is managed automatically. To temporarily adjust the allocation of storage and program memory, move the slider.
设备可自动管理内存。要临时调整存储和程序内存的分配，可移动滑块。
Memory allocated to a memory area Each memory area created by an application is allocated with a requested size.
分配给内存区域的内存应用程序创建的每个内存区域会被分配所申请的内存大小。
When allocating memory from the heap, the contents of that memory are garbage — whatever bits happen to be left over from the last time that memory was used.
在从堆中分配内存时，不管上次使用内存之后留下了什么内容，内存中的内容都被当作垃圾。
Application Shared memory: This refers to the memory allocated when an application connects to a database and is used by agents that do the work requested by the connected clients.
应用程序共享内存：这是在应用程序连接到数据库时分配的内存，由处理连接到数据库的客户机所请求的工作的代理使用。
Database Shared memory: This refers to the database global memory, which is allocated when the database is activated or connected to for the first time.
数据库共享内存：这是数据库全局内存，是在激活数据库或者第一次连接到数据库时分配的。
Each application connected to the database has memory allocated to it; therefore accurate configuration of the parameters affecting the application Shared memory becomes crucial.
每个连接到数据库的应用程序都会被分配内存；因此，正确地配置会影响应用程序共享内存的参数非常重要。
The data can normally be recorded in internal memory or to a memory card for later transfer to a computer.
数据通常可记录到内置存储器或记忆卡中，以便日后传输到计算机。
Memory usage problems due to insufficient memory resources can be caused by configuration issues or system capacity issues.
由于内存资源不足而产生的内存使用问题可能是由于配置问题或系统容量问题所导致的。
Just like with other forms of UNIX, AIX employs virtual memory structures to help complement physical memory.
与其他风格的UNIX一样，AIX也使用虚拟内存结构帮助补充物理内存。
For example, each processor has its own memory but also access to Shared memory with a different access latency.
例如，每个处理器拥有自己的内存，访问共享内存时具有不同的访问延迟。
Before executing, the test adjusts its total memory usage according to how much real and virtual memory exist on the system.
在执行之前，测试会根据系统中存在多少物理和虚拟内存来调整其总的内存使用情况。
Look for the true memory size in the output of different tools to determine the actual memory available without compression.
要想查明在不压缩的情况下可用的实际内存，应该在不同工具的输出中寻找真实内存大小。
Even though the data segment maps a file, it is a private memory mapping, which means that updates to memory are not reflected in the underlying file.
尽管数据段映射了文件，但这种内存映射是私有的，也就是说，数据段的内存更新不会在其映射的文件中生效。
The processor retrieves data from the memory, performs an operation on it, then returns it to memory.
处理器负责从存储空间中读取数据，进行数据计算，并将结果返回给存储空间。
