摘要
Web应用程序的分布式和多用户特性使得性能问题成为需要关注的重要问题，由于web浏览器的灵活通用性，用户无需安装客户端等优点，web应用程序一旦交付使用，用户数将很容易增加，但是要保证在增加这些额外的用户后你的程序仍会运行良好，就需要做些性能优化方面的努力了。通过利用页面缓存和数据库连接池以及一些其他java编程方面提高效率的手段和建议，可以显著提高和实现对web应用程序的性能优化。
Because of the distribution and multiply users peculiarity of J2EE web application, the performance issue become more and more important. Once a J2EE web application is ready and be used, there is no need to install any client app, instead of, any web browser can access the web application which is widely used in personal computer. So the amount of users can easily increased, to make sure the web application can running good under this situation, some performance tuning should be done. Page cache, database connection pool and other way of java coding can observably optimize the performance of J2EE web application.
