Java EE (Java Enterprise Edition) General Discussion

Hi,
I am using javamail to retrieve incoming mails. With the below code it's taking 4.5 to 5 sec to receive 23 emails.
To connect to the store it's taking 3.5 to 4 seconds.
I have checked with thunderbird, mails receive in milli seconds.
Is there a way to reduce time?
How much time does it take usually to receive 25 mails using imaps?

  Properties properties = new Properties();
                properties.put("mail.store.protocol", "imaps");
                properties.put("mail.host", host);
                properties.put("mail.port", "993");
//                properties.put("mail.imaps.fetchsize", "3000000");
                properties.put("mail.imaps.ssl.enable", "true");
                Session emailSession = Session.getInstance(properties);
                Store store = emailSession.getStore("imaps");
                if(!store.isConnected()){
                    System.out.println("not connected");
                    store.connect(username, pwd);//Here takes 3.5 to 4 seconds
                    System.out.println("time taken store connect: "+System.currentTimeMillis());
                }System.out.println("connected");

                // create the folder object and open it
                Folder emailFolder =store.getFolder("INBOX");
                emailFolder.open(Folder.READ_WRITE);

                FetchProfile fp = new FetchProfile();
                fp.add(FetchProfile.Item.ENVELOPE);
                fp.add(IMAPFolder.FetchProfileItem.FLAGS);
                fp.add(IMAPFolder.FetchProfileItem.CONTENT_INFO);
                fp.add(UIDFolder.FetchProfileItem.UID);

        emailFolder.fetch(emailFolder.getMessages(), fp); // Load the profile of the messages in 1 fetch.
//        emailFolder.doCommand(new CustomProtocolCommand(start, end));
                for (final Message message : emailFolder.getMessages()) {
                    System.out.println("message"+message.getSubject());//Here takes 4.5 to 5 seconds
                    System.out.println("time taken message: "+System.currentTimeMillis());
                }
