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。
Again, you want the file memory paged to disk and not the computational memory.
同样，您希望将文件内存分页到磁盘中，而不是计算性内存中。
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。
The memory manager allocates memory to threads in chunks to minimize contention on the heap lock.

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)。
These memory areas are referred to as scoped and immortal memory.

I discuss how AIX USES virtual memory to address more memory than is physically on your system.
我将介绍AIX如何使用虚拟内存来寻址比系统中物理内存更大的内存。
We discuss how AIX 7 USES virtual memory to address more memory than is physically on your system.
我们将介绍AIX7如何使用虚拟内存来寻址比系统物理内存更大的内存。
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。
This memory to memory copy is relatively slow compared to the speed of the processor.
与处理器的速度相比，这种内存到内存的复制相对比较慢。
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。
The third option is the OG memory to memory solution.
第三个选项是OG内存到内存解决方案。
The processor is connected to physical memory by the memory bus.
处理器通过内存总线连接到物理内存。
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。
But since instance memory is generally small compared to database memory, this gain is beneficial.
但是由于实例内存与数据库内存相比通常比较小，因此这样可以获得好处。
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。
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.
总内存较少的空闲内存阈值超过分配给所有虚拟机的内存总数。
