JBoss SOA5.3.1 - ESBScheduler High CPU utilization

[joe_boy12]

Hello folks - I am trying to find root cause for high CPU utilization time for one of the worker threads. we receive too many files at at time around 300 of them - and we are using fs-listener and esb-listener pair - maxThread is 2 (latency is not an issue). we see huge CPU usages during that time. any insights?

Have you done any profiling with JProfiler or something like that?    That's probably the next step I would take.
