Amazon S3 issue in web applications

Please have a look at the below code.

   public class S3Test extends HttpServlet {

    /**
     * Processes requests for both HTTP <code>GET</code> and <code>POST</code>
     * methods.
     *
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        String accessKey = "************";
        String secretKey = "****************";

        AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
        AmazonS3 conn = new AmazonS3Client(credentials);

        System.out.println("done");

//        List<Bucket> buckets = conn.listBuckets();
//for (Bucket bucket : buckets) {
//        System.out.println(bucket.getName() + "\t" +
//                StringUtils.fromDate(bucket.getCreationDate()));
//}
    }
}

I am using this code to list the buckets I have in amazon s3. However this process is extremely slow, it takes almost 1 minute or more. Not only that, this takes lot of memory, almost freezing the Google Chrome. My bucket is in US standard region and my application is running in a PC located in south asia.

The delay is in connection configuration.

I am using Netbeans IDE and the above code is a part of a servlet. The server I am using is apache tomcat 7.

Any ideas why this is taking this much of time? I added all the JAR files came with Amazon SDK for Java as well. It has no use to me if this takes this long.

SPECIAL NOTE

I noticed this is not taking any time delays when it is running in non web java applications. I ran this in a simple Main class which is not web based, and it worked fine, fast. What is really happening here?
