Socket client running slow in stateless bean 3.0

[jhavefun]

I found the socket client inside of SLSB 3.0 takes more time to connect to a server which is implented by c++. but the same code works very fast on Tomcat .
actually the code is very simple:

 Socket socket = new Socket(host, port);
 OutputStream outputStream = socket.getOutputStream();
 InputStream inputStream = socket.getInputStream();
 outputStream.write(outPacket);
 socket.setSoTimeout(15000);
 int messageBufferSize = 250;
 byte[] res = new byte[messageBufferSize];
 int len = inputStream.read(res);
 return res;

Is there any other solution for EJB 3 in JBoss 4.2.3 instead of pure socket client? or how can I optimise my ejb?

thanks.
