I think I plotted graphs properly this time.
1. When set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m 
Graph is http://img169.imageshack.us/img169/6715/withoutyoung.jpg 

2. When set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m -XX:NewSize=300M -XX:MaxNewSize=300M -XX:SurvivorRatio=32 -XX:+UseTLAB -XX:TLABSize=64K

The server machine is having 4 processors. 32 bit JVM.

What is meant by CMS collection?
You mean using Concurrent Collector (Using -XX:+UseConcMarkSweepGC -XX:+UseParNewGC options)?

Btw, I configured the HttpConnector with maxthreads=600.
(I arrived at this number after monitoring the busy threads using JMX Console)
