C# SocketAsyncEventArgs High Performance TCP/IP Server and Client

Need TCP/IP server and client pair using SocketAsyncEventArgs. We currently employ a few variations of the same code, uses a thread for each connection which is not up to par to process a lot of data, our business has grown and we need something that works better. We send messages between client and server separated by a delimiter, some messages are sent from one user to the other some are meant for other things. We need to be able to track connected clients properties, process messages that are coming in (parse), depending on what message is take appropriate action. We will do our own logic, but what we need is well built skeleton for us to use in a few applications with sections explained to us: this is where you process the string that came in (compare to ...), this is how you set/get connected clients properties, this is how you send to one or all or certain clients message. I am attaching a skeleton we have been using. In File [login to view URL] look at functions ParseReceiveBuffer and ProcessClientData, really would like to get something in similar format. I have found this: [login to view URL] it seems it should do what we need, just no time to invest into learning at the moment. Thank you.
