Hey Ramesh,

Based on your post I can see that you are stepping into the chat world.
As of Widlfire 3.2 (open source XMPP server) we are using MINA as our
networking layer. In our performance tests we got 30K-40K concurrent
users sending heavy load to the server and everything went fine. We were
not able to get more clients since the client load testing tool was not
able to generate more.

In case you want to give Wildfire a try you can get it from:

If you want to build your own client then you can use the Smack library
(open source too) that provides a user friendly high-level API. Link to
Smack: http://www.igniterealtime.org/projects/smack/index.jsp. Or you
can just use any XMPP client
(http://www.jabber.org/software/clients.shtml) or our provided Spark
client (http://www.igniterealtime.org/projects/spark/).

Subject: Performance Test

Hi All,

        I have doing some performance testing for mina chat application.

I have used chat server, it will send(broadcast)  data to the connected
clients.Except one client which is the data provider for server and all
other clients are receiver.I have simulated the message provider client

to sent message to server by thread. Wahat i problem is ,and also
receiving client i also simuldated by thread.when no of client
connection reaches 250.The server will stop the client(closes the
session). Here is my server code that process and sent message to
connected client.

             synchronized( sessions )
            Iterator iter = sessions.iterator();
            while( iter.hasNext() )
                IoSession s = ( IoSession ) iter.next();
                if( s.isConnected() )
                    s.write( message);

and this is my client simulation code

public void run() {
		while(true) {
			connector = new SocketConnector();
		SocketAddress address = parseSocketAddress(
        String name = "chells";
        handler = new ChatClientHandler( Client.this );
        client = new ChatClientSupport( name, handler );
        //nameField.setText( name );
        //serverField.setText( dialog.getServerAddress() );
        if( !client.connect( connector, address, false ) )
			prtMsg("Could Not Connect To Server ");

		}catch(Exception e) {
			prtMsg("Exception in run ------------>"+e);
