除了增加数据库容量外，对大型RID的支持还简化了表空间的管理(通过合并)，并可以提高存储和内存的利用率。
In addition to increasing database capacity, large RID support can also simplify table space management (through consolidation) and improve storage and memory utilization.
为了提高效率，如果由硬件管理虚拟内存，内存是按照所谓的内存页方式进行管理的(对于大部分体系结构来说都是4kb)。
For efficiency, given the way that the hardware manages virtual memory, memory is managed in what are called pages (4kb in size for most architectures).
SACOS的动态内存管理方法可以有效地减少内存管理开销和内存碎片，提高内存的利用率。
The dynamic memory management of SACOS can decrease efficiently the memory management overhead and memory fragmentation and improve the memory utilization.
通过在具有大型数据结构的面向对象程序中引入自动内存管理算法，可以提高这类程序的开发质量与效率。
By employing automatic memory management algorithm in object oriented program with large data structure, the developing quality and efficiency of this kind of software are improved.
为了提高CPU的速度和更有效的管理物理内存，一般都采用转换查找缓冲器（TLB）将虚拟地址转换为物理地址。
In order to optimize performance, including speed and the usage of its memory, CPU usually hires a Translation Lookaside Buffer(TLB) to translate the virtual address into physical address.
同时，内存管理器排除了出现零碎内存的可能性，并增大了内存引用区域以进一步提高性能。
Meanwhile, the memory manager removes the possibilities of fragmented memory and increases memory locality-of-reference to further increase performance.
这种缓存结构同传统的相比，缓存命中率有所提高，内存消耗变小了，同时大大改善了本地缓存空间的可管理性。
Compared with the traditional structure, it not only USES less memory, also improves the administration of local cache space.
