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。
Another advantage is that this solution can handle cascading failures of application servers, which is only possible with more than one replica in a memory to memory configuration.
此解决方案的另一个优势是能够处理应用服务器的级联故障，而这在内存到内存配置中只有使用多个副本才有可能实现。
However, for systems in which a large number of processes are running, storing page tables in high memory can be enabled to squeeze more memory out of the low memory area.
不过，对于那些在大量进程在运行的系统来说，将页表存储到高端内存中可以在低端内存区域挤出更多的内存。
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。
Memory allocated to a memory area Each memory area created by an application is allocated with a requested size.

Each new memory allocation requires updates to the memory Pointers, and as this happens more and more, it creates more and more resource consumption.
每个新内存分配都需要到内存指针的更新，而随着这一动作发生得越来越多，会带来越来越多的资源消耗。
The mapping of virtual memory to physical memory occurs through page tables, which are implemented in the underlying hardware (see Figure 1).
虚拟内存到物理内存的映射通过页表完成，这是在底层软件中实现的(见图1)。
I discuss how AIX USES virtual memory to address more memory than is physically on your system.

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。
Because each process (and the kernel) can have identical addresses that refer to different regions of physical memory, it's not immediately possible to share memory.
因为每个进程(和内核)会有相同地址指向不同的物理内存区域，不可能立即共享内存。
By default, the system does not allocate any memory to the large page physical memory pool.
在默认情况下，系统并不为大页面物理内存池分配任何内存。
AIX 7 USES all available memory, except memory that is configured to be unallocated and known as the free list.
AIX7使用所有可用的内存，除了那些配置为未分配并用作空闲列表的内存之外。
For most USES, pages of this size are the most efficient way for the memory manager to deal with memory.
对大部分用途来说，内存管理器以这样大小的页来管理内存是最有效的。
The memory cleaner would essentially free up memory by dumping to the virtual memory, so make sure you don’t use it when you are working in an application.
内存清理工具会有效的通过利用虚拟内存来释放内存，所以当你使用应用程序的时候注意不要使用这个功能。
He was particularly interested in a type of memory called episodic memory, which relates to specific events, places and times.
他的兴趣点在一种叫做“事件记忆”的记忆上，这种记忆与时间、地点和次数相关联。
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。
This can result in unexpected additional memory usage, causing memory-area limits to be exceeded.
这可能导致意外的附加内存使用，导致内存使用超出内存区域限制。
When configuring IDS memory, we need to consider the total available memory, both physical RAM and virtual memory and daily load on the system.
在配置IDS内存时，我们需要考虑总的可用内存，包括物理ram、虚拟内存和系统上的日常负载。
The performance of database persistence is also better than memory to memory replication, when not taking the extra hardware that the database is running on into account.
在不考虑数据库运行所需的额外硬件的情况下，数据库持久性的性能也好于内存到内存复制。
Given the alternative, you would much rather have file memory paged to disk than computational memory.
在可以选择的情况下，更希望将文件内存换出到磁盘，而不是换出计算内存。
Total memory less the free memory threshold exceeds the total amount of memory assigned to all virtual machines.
