Scenario 1: Eliminating bottlenecks
The response time of application A becomes unacceptable once the server is experiencing modest throughput. You see that much of the resident time is spent idle. To see if the cause is a bottleneck in the application server pools, use System Resources during these times to view the percentage of threads used in the Database Connection Pools, Thread Pools, and JCA Connection Pools. If any pool is at or near 100%, it is likely that demand for application A is saturating those resources. You might be able to fix the problem by creating more or larger pools.
