随着当今社会信息化程度的提高，企业对信息系统的功能和性能要求越来越高，系统的性能优化是依赖于信息系统分析与设计、系统开发、系统运行与维护、系统更新四个阶段。在众多企业信息系统的设计和开发过程中，仅关注系统功能的实现，在系统优化方面考虑较少，将系统优化的重点放在系统运行和维护阶段。这造成系统被“救火式”优化，只能治标不能治本或造成系统优化的成本巨大，甚至系统无法优化，导致系统不得不提前下线。本文就如何在信息系统全生命周期的性能优化进行了一些探讨，提出各阶段性能优化的若干策略，并结合实际应用进行详细说明。
隨著噹今社會信息化程度的提高，企業對信息繫統的功能和性能要求越來越高，繫統的性能優化是依賴于信息繫統分析與設計、繫統開髮、繫統運行與維護、繫統更新四箇階段。在衆多企業信息繫統的設計和開髮過程中，僅關註繫統功能的實現，在繫統優化方麵攷慮較少，將繫統優化的重點放在繫統運行和維護階段。這造成繫統被“救火式”優化，隻能治標不能治本或造成繫統優化的成本巨大，甚至繫統無法優化，導緻繫統不得不提前下線。本文就如何在信息繫統全生命週期的性能優化進行瞭一些探討，提齣各階段性能優化的若榦策略，併結閤實際應用進行詳細說明。

With the advancement of informationization in our society, the Information system of function and performance required more and more. System performance optimization was dependent on information system analysis and design, system development, system operation and maintenance, system updates four stages. During information system design and development of numerous enterprises, the system function was concerned but the system optimization was few concerned. The system optimization only was focused on system operation and maintenance stage. This causes the system to be“fire-fighting”optimization, only suppress the symptoms not the illness or cause the system to optimize the cost was huge, and even the system cannot be optimized, and the system was forced to retired early. This article on how to optimize the performance of the whole life cycle of information system were discussed, some strategies were put forward to optimize the performance of each stage, and combining the practical application in detail.
