Thread: Need help finding Fast Way to send a message to multiple sockets in a list object?

Im making a chat application, i already finished it but sometimes the messages are REALLY delayed for some clients. I have two methods, one called checkForMessages that checks the message on the sockets, and sendMessages which sendsthe message to all sockets. I have a list object of sockets that keeps trakc of the connections.

Here is my code for both methods
(this is the server code btw)

Code:

public void checkForMessages(List<Socket> s)
        {
            Byte[] byteBuffer = new Byte[1024];
            bool result;
            for (int i = 0; i < s.Count; ++i)
            {
                result = s[i].Poll(1000, SelectMode.SelectRead);
                if (result)
                {
                    Array.Clear(byteBuffer, 0, byteBuffer.Length);
                    s[i].Receive(byteBuffer);
                    sendMessages(s,byteBuffer);

                }
            }
        }



public void sendMessages(List<Socket> s,Byte[] bufferMessage)
        {
            for (int i = 0; i < s.Count; ++i)
            {
                    Socket sendMessage = s[i];
                    sendMessage.Send(bufferMessage);
            }



        }

Is there any other way i can send/recieve messages without it being so delayed sometimes?!
