Michael, according to the first message in this thread all machines have 36 cores. The thing is that client threads call cache operation and wait for response from server. So, most of the time client is waiting. I would have at least 36 * 4 threads on client side. And also start more clients. I think it is almost impossible to fully utilize resources of 2 servers from only client. Can we start 3-4 clients?
