tomcat 优化到每秒并发1000
现在系统部署只能达到240+ , tomcat + apache 也只能到 900 + ，看到robbin的发帖能达到1000 ，不知道该如何配置，特来请教：http://www.iteye.com/post/370111?page=8
robbin 写道
既然你用tomcat4都可以达到并发600，那tomcat5.5在同样环境下经过调优完全可以达到1000，看来问题还是在于你们tomcat没有配置好。
附带环境配置如下：
环境配置如下: （jdk没有用 -server）

单独测试tomcat基本上只能达到240+左右的并发，tomcat+apache 900+并发，如果是静态页面tomcat并发1000+没有任何问题。
tomcat基本上都保持在 20% - 45% 之间 ， 内存在 80M -- 600M +之间 ，根据并发和请求的大小，内存的变法比较明显，cpu基本保存在这里，apache占用的cpu基本上是在 15% - 40%。
因为JRockit收费，所以就没有测试。（主要是真实部署的时候会采用这些配置，收费的公司目前也不会购买！^_^）
