摘　　要：为了提高舆情采集系统的性能,通过分析舆情采集系统的需求与架构,针对系统存在的性能瓶颈,提出了相应的优化方案,设计并实现了分布式缓存系统,即在现有分布式搜索引擎基础上,在总查询处理服务器与各集群子查询处理服务器之间增设一台缓存服务器。实验表明,在采用该分布式缓存系统后,舆情采集系统的处理能力得到了一定程度的增强。In order to improve the performance of the public opinion collection system, requirements and architecture for the system are analyzed. Aiming at performance bottlenecks of the system, opti- mization schemes are proposed, and a distributed caching system is designed and implemented, that is, a cache server is added between a total-query processing server and sub-query processing server within each cluster on the basis of the existing distributed search engine. Experiments show that the processing capacity of the public opinion collection system has been increased to a certain extent af- ter using the distributed caching system.
