> While testing the driver's performance I found that transmission of small messages from client to server capped at about 50/second due to it not enabling "tcp nodelay" on its socket.  The default tcp/ip socket setting is to stall a little to see if the client is going to send another message, enabling tcp/ip to fill an MTU.  In the case of the current Protobuf driver this is never going to happen so this jitter should be disabled with Socket.setTcpNoDelay(true).
