数据库系统的性能最终决定数据库的可用性。因此而言数据库的性能是数据库的发展的生命力。在我们对于数据库的使用过程中，数据库在运行一段时间后都会存在一定的性能问题，该文主要针对数据库性能的五个方面进行分析和说明，分别是整体吞吐量问题、用户响应时间问题、内存比例问题、磁盘的输入输出问题、数据库的命中率问题，最后针对数据的优化策略进行分析，同时为我们数据库性能调整与优化提供相应的理论支撑。

The final decision on the performance of database systems database availability. Therefore, in terms of performance of the database is a database development vitality. In the course of our database, the database will be some performance problems af-ter running for some time, the paper mainly for the five aspects of database performance analysis and explanation, namely, the overall throughput issues, user response time issues, memory proportion problem, the problem of disk input and output, the hit rate of the database, the final analysis of data optimization strategy, while providing appropriate theoretical support for our data-base performance tuning and optimization.
