用JAVA多线程技术编写数据库压力测试程序

在使用数据库的WEB系统中，客户端和数据库建立连接的速度会随着客户端数目的增加而变慢，影响了WEB应用程序响应客户请求的时间。为了测试客户端数量和建立数据库连接所消耗时间的关系，通过设置线程的数量来模拟多个客户端，同时访问数据库的情况，进而对数据库在多客户情况下所表现出的性能进行分析。

Program for testing database with the technology of Java's multi - thread

In a web- system of using database,the speed that client connects to database will become slow when clients increase,which affects the time that the web program feedbacks the client's request (of course,a network and the other factors can affect it,too). In order to test the relation between the client number and the consumed time of establishing database connection, by using the method of multi-thread of Java language to simulate the environment that many customers access the database at the same time and by setting the number of threads,this paper analysed the performance of database.
