Subject Re: is tens of thousands of session feasible?
Date Wed, 05 Mar 2014 09:46:19 GMT
If I have one session and a receiver thread. this thread receive ten
messages to ten worker thread.
each worker thread acknowledge it's message?
receiver thread:
while(true){
      Message msg=receiver.receive();
      put msg to a ConcurrentLinkedList;

Worker thread:
while(true){
     Message msg=getMessgeFromLinkedList();
     process msg;
     msg.acknowledge();
}
