基于数据库连接池的数据库访问性能对比测试研究

一般认为，数据库访问中采用连接池技术在并发性能的处理上以及用户时延的等待上都有很大优势。但使用连接池到底在数据库访问性能上有什么样提高，缺乏数据上的支持。通过三种不同的数据库访问模式下的性能对比测试，对基于连接池的数据库访问性能的提高给出一个定量的数据，该测试对于数据库访问的性能提高有重要参考价值。

Performance Comparison Test of Database Access Based on Database Connection Pool

Is generally believed that the use of connection pool database access technology in the handling of concurrent performance,and user has a significant delay waiting on the edge.But in the end use of the database connection pool to access any kind of performance increase,the lack of data support.In this paper,three different database access mode,the performance comparison test,the database connection pool based on the improvement of access to give a quantitative performance data,the test performance improvement for database access has important reference value.
