When I look at the CPU usage I see that it never exceed 100%, except at the startup, the CPU utilization may reach 170%. I installed several scripts in order to record the load average of CPUs, memory usage... but all the time, only one cpu is busy. What is the kind of tests that I should do to make sure that jboss take advantage of all the processors of the machine? thanks for your help.
