应用传统的算法和启发式方法很难维护，因为随着时间的推移，系统的性能下降使系统变得难以控制。
Traditional methods of applying dedicated algorithms and heuristics result in hard to maintain, unwieldy systems with performance degradation over time.
尽管这句话通常是正确的，但是性能分析和优化机会分析应当成为每个应用程序的部署和维护流程的一部分。
Although this is often true, performance analysis and investigating opportunities for optimization should be a part of every application's deployment and maintenance process.
这么做的好处包括灵活性、保持应用程序易于维护、代码重用和更好的性能。
The benefits of doing so include flexibility, keeping maintenance of the application easy as it grows, code reuse, and better performance.
