请大家帮忙分析一下这台小机性能瓶颈处在什么地方

vience

服务器配置情况如下

4路 IA2 9015 处理器
16GB 内存
300GB X 3 SCSI 10K RPM 硬盘

运行的服务

Apache 2.2 相应 HTTP 请求
Geronimo 1.1 接受 MOD_JK 转发的 JSP 请求 配置了JDBC连接池
MySQL 5.0 数据库

服务器目前运行的top数据如下

这是详细的top运行情况

从运行情况来看 CPU 计算能力可以完全的满足要求 瓶颈应该是出在 内存 和 磁盘IO上

求助论坛的大虾给我一些意见

谢谢

java web服务是用tomcat吗?
高负荷还是用resin吧.
