The physc value shouldnt cross more than the entitled capacity of server... Here E.capacity is 1.5... But, physc is crossing more than 6.... So, server is taking CPU from shared pool.
More over, we need to take care of "app" value, (available physical processor), There should be enough physical processor in the shared pool.
