Hi, I would like to try this example, however my attempts to build on Win 8.1 using VS 2013 update 3, however the following errors (below) resulted.

I am new to tcp and sockets. I developed an Csharp echo-server and client using SocketAsyncEventArgs and TCP. Running a test using the Csharp server and client with 10 client connections, it transmits and receives back 1 million messages in 12.34 seconds. This is running on a quad-core Win 8.1 laptop. I am investigating RIO and tried your server with my csharp client. using the same parameters and machine as with the above Csharp test, it took 200 seconds (versus 12.24 seconds). Testing again with 4 connections, it took exactly the same time for 400,000 messages as it took for one million (200 seconds).

While I am continuing to investigate the possible reasons for this, I thought I should post this to determine if there is an obvious reason. I do prefix the message with the message length which my server tests to determine if/when the message has been fully received. Without looking further there appear to be two anomolies (1) the excessive time taken, and (2) the fact that using a smaller number of connections and messages, it took the same time to complete.

ClientSession.obj : error LNK2019: __imp__closesocket@4 외부 기호(참조 위치: "public: void __thiscall ClientSession::Disconnect(enum DisconnectReason)" (?Disconnect@ClientSession@@QAEXW4DisconnectReason@@@z) 함수)에서 확인하지 못했습니다.

등의 컴파일 에러가 다수 뜨네요.
