Data is not delivered at server after socket.Send C#

I have written a socket client program at my end in which i am sending data in a loop to the server.But when i m sending data i a loop through "socket.send(buffer);" the data is not delivered to the server side.

If i provide a bit of sleep between two data packet then it is delivered properly.But my that sleep is very critical for my application.I need to send packet at the same time when it is initiated.Its a financial domain application so delivery at same time is required.


some code sample:--

IPEndPoint ipep = new IPEndPoint(IPAddress.Parse(Ip), Convert.ToInt32(port));
Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);


public void GetConnectedServer()
{
server.Connect(ipep);
}

public void SendData(byte[] data)
{
int sentbytes = server.Send(data,SocketFlags.None);
}

public byte[] RecvResponse()
{
  byte[] recBuffer1 = new byte[1024];
  try
  {
    int recvBytes = server.Receive(recBuffer1, SocketFlags.Peek);
    recBuffer1=new byte[recvBytes];
    recvBytes = server.Receive(recBuffer1, 0, recvBytes, SocketFlags.None);
   }
   catch(SocketException ex)
   {
   throw ex;
   }
return recBuffer1;
}

Above is the client fucntions used for coomunication to the server.My receive is working fine.
