socket.outputStream is taking so much time why?

Hi I have written a server in Android. The following is my code:-

SSLServerSocket ss=(SSLServerSocket)sslssf.createServerSocket(Constants.CHAT_SERVER_PORT);
final String[] enabledCipherSuites = { "SSL_DH_anon_WITH_RC4_128_MD5" };
ss.setEnabledCipherSuites(enabledCipherSuites);         
while(true) {
    Socket s=ss.accept();
    OutputStream out=s.getOutputStream();
    ObjectOutputStream oos=new ObjectOutputStream(out);
    oos.flush();
    Android android=new Android();
    oos.writeObject(android);
    InputStream sis= s.getInputStream();
    ObjectInputStream ois=new ObjectInputStream(sis);
}

Everything is going fine. But "OutputStream out=s.getOutputStream();" in the above code is taking signifacant amount of time. Nearly one minute. I am not sure why? Please help me solving this problem?

The following is the corresponding client code(desktop):-

    SSLSocket socket= (SSLSocket)sslsf.createSocket(ip,Constants.CHAT_SERVER_PORT);
        final String[] enabledCipherSuites = { "SSL_DH_anon_WITH_RC4_128_MD5" };
        socket.setEnabledCipherSuites(enabledCipherSuites);         
        InputStream in=socket.getInputStream();     
        OutputStream out=socket.getOutputStream();          
        ObjectInputStream ois=new ObjectInputStream(in);            
        ObjectOutputStream oos=new ObjectOutputStream(out);         
        Object obj=ois.readObject();                
        SocketInfo sockInfo=new SocketInfo(socket,oos,ois,ip);

Kindly help me in this issue.

That will be the SSL handshake taking the time. If Android supports javax.net.debug=ssl,handshake you can see into it to learn more.

But why are you using an anonymous cipher suite. Are you aware it's insecure?
