I am running a Java Application on JBoss-4.2.2 deployed on two 2GB machines. In the application, there is a Quartz job that sends a https request to two systems and gets response. By default, it had 10 worker threads. I updated quartz.jar to make it 2 worker threads. These threads starts low, after some weeks if I check using listThreadCpuUtilization() MBean, the first thread is taking 44140 CPU cycles, and second thread is taking 229187 CPU cycles. Is this normal? The changes I made (reducing 10 worker threads to 2 threads) could have adversely affected the performance? Thanks, Jackie.
