Question

I am using the following code taking me 18 hrs browsing 1 lac (=100,000) message: I need it in minutes to complete, How can i make it fast complete browsing in 30 mins ?

Integer count = (Integer) jmsTemplate.execute(new SessionCallback() {
            public Object doInJms(Session session) throws JMSException{
                   QueueBrowser browser = session.createBrowser((Queue) jmsTemplate.getDefaultDestination(), messageSelector);


                Enumeration messages = (Enumeration) browser.getEnumeration();

                while (messages.hasMoreElements()) {
                    count++;
                    Message message = (Message) messages.nextElement();
                    TextMessage tm = (TextMessage) message;
                    String messageBody = tm.getText();

                 } }
