本小节提供调优系统性能的建议，包括内存和分页、磁盘配置以及连接器。
This section describes recommendations for system performance, including memory and paging, disk configuration, and connectors.
性能度量的第二个用途是，判断调优是对系统性能有帮助，还是使它更糟糕了。
The second use of performance measurements is to determine if tuning has helped the situation or made it worse.
内存调优也可能极大改善系统性能，减少额外的分页空间需求。
Memory tuning can also bring significant improvements in system performance and reduce the need for additional paging space.
