【摘要】：近些年软件行业的发展，人们对软件的要求已由原来的功能支撑方面逐渐转向性能方面。即不仅追求“有”，而且更加追求“好”和“快”。同样，随着中国移动公司业务的快速发展，移动业务支撑系统必须在性能方面给予足够的支撑。面对中国移动的用户量和业务量的快速增长，目前移动CRM(CustomerRelationship Management，客户关系管理)系统逐渐暴露出由于性能而引发的问题。特别是在月初和月末时，系统访问量骤增，导致系统性能急骤下降。因此，对移动CRM系统进行性能分析和优化对提高移动的运营支撑能力，将具有非常重要的意义。本文首先介绍国内外常见的几种缓存技术，并给出相应的优缺点。然后针对Memcached做了相关的介绍，为后面的改造打下基础。接着对移动CRM的性能现状进行分析，指出严重影响性能的瓶颈，并针对瓶颈，详细描述了如何运用Memcached来解决瓶颈来提升支撑系统的性能。主要包括Memcached缓存结构的设计、数据的装载策略、API(Application Programming Interface,应用程序编程接口)的封装、支持大数据对象改造，以及对移动CRM系统的具体改造。最后通过对系统进行改造前后的性能测试比对，，以体现Memcached对移动CRM性能提升的有效性。最后得出结论，Memcached对解决类似的大型系统的性能问题都具有十分重要的实际意义和科学意义。
[Abstract]:In recent years, with the development of software industry, the demand for software has gradually shifted from the original functional support to the performance. That is, the pursuit of not only the "have", but also the pursuit of "good" and "fast." Similarly, with the rapid development of China Mobile's business, the mobile business support system must provide sufficient support in terms of performance. In the face of the rapid growth in the number of users and business of China Mobile, the current CRM (CustomerRelationship Management, customer relationship Management (CRM) system has gradually exposed the problems caused by the performance. Especially at the beginning and end of the month, the system access increased sharply, resulting in a sharp decline in system performance. Therefore, the performance analysis and optimization of mobile CRM system will be of great significance to improve the operation support capacity of mobile. This paper first introduces several common cache technologies at home and abroad, and gives the corresponding advantages and disadvantages. Then for the Memcached to do a related introduction, for the later transformation laid the foundation. Then it analyzes the current performance of mobile CRM, points out the bottleneck that seriously affects the performance, and describes in detail how to use Memcached to solve the bottleneck to improve the performance of the support system. It mainly includes the design of Memcached cache structure, the encapsulation of data loading strategy, API (Application Programming Interface, application programming interface, the support of big data object transformation, and the concrete transformation of mobile CRM system. Finally, the effectiveness of Memcached in improving the performance of mobile CRM is demonstrated by comparing the performance of the system before and after modification. Finally, it is concluded that Memcached is of great practical and scientific significance in solving the performance problems of similar large-scale systems.
