疯了，Apache+Tomcat负载均衡比单个Tomcat反应慢

主机虚拟机，2g内存，一般服务器配置，windows server 2003平台。

因要集成php，而原先的系统是用java开发的，所以考虑使用apache+tomcat(VirtualHost方式)作负载均衡，另外用一个VirtualHost解析php，配置里面用到了mod_deflate，proxy，cache相关模块，静态页面、图片、js文件、css文件等由apache负责，现在各模块都能正常工作了，但唯一的问题就是访问apache提供的静态页面或图片打开速度比直接使用tomcat提供静态页面的要慢一倍以上，几乎没法正常使用。什么优化配置都试过了，还是不行，不知道各位大侠有什么办法，请教一二！以上均在同一台机器上做试验。
