Pacifica also amends address translation with host and guest memory management unit (MMU) tables.
它使用一种有效的算法压缩仓库表并将它们存储在内存中。
It compresses warehouse tables with an efficient algorithm and stores them in memory.
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。
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.
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)。
The mapping of virtual memory to physical memory occurs through page tables, which are implemented in the underlying hardware (see Figure 1).
对于这个报告,你需要显示每个用户当前的内存使用情况图,然后在一个表中按照每个会话将内存使用划分。
For this report, you want to display a graph of total memory usage per user and then, in a table, break that memory usage down on a per-session basis.
这些统计信息存储在表示声明的临时表的目录信息的内存结构中。
These statistics are stored in memory structures that represent the catalog information for declared temporary tables.
操作系统通过一个内部表将处理器地址空间中的内存段映射到内存页,该表定义哪些内存段由哪些处理器所拥有,等等。
Operating systems map memory segments in a processes' address space to memory pages through an internal table which defines what memory segments are owned by what processes, and so on.
在该方法中,需要扫描其中的一个表,通常扫描较小的那个表,用它在内存中创建一个哈希表。
In this method, one of the tables, usually the smaller one, is scanned and used to create a hash table in memory.
在构建阶段,数据库服务器读取一个表,并且在应用所有现有筛选器之后,在内存中创建一个哈希表。

虽然在第一行中,针对引擎的大小来对内存做了考虑(118,812KB),但是,我们没有使用很多内存,我们为表保持缓存。
Although looking one line higher at the size of the engine in memory (118,812 KB), we aren't working with a lot of memory, Let's keep cache on the table.
