求助各位大神　java程序运行变慢的问题

avxiuwanmm 2014-06-01 12:01:09

小弟最近帮家里开发一个小的管理软件，刚开发的头几天反应都快，但到后来加载页面的时候特别慢。

　　struts2+sql server2005
ajax通信都很快的反应。提交刷新画面会慢下来。重启电脑也慢。不知道那里有问题。
　　
　　　我在后台打印，整个action很快跑完了，就是跳转到页页加载的时候特慢。

先贴代码吧。
== 首先从这里跳转到600100struts 配制文件===================================

　　后来我从新装了下电脑系统之后，速度又变正常了。但我发觉电脑ＣＰＵ内存都很充足。
　　谁知道有什么可能造成的吗？
