Httprest performance improvement

I am doing a HTTPRest post call to send the data to a third party, my data is in the order of 3 to 10 million and i can send only one record per request along with username and password for authentication as specified by third party

sample code that i am using is 

public static void main(String[] args) {

  try {

    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpPost postRequest = new HttpPost(
        "http://localhost:8080/RESTfulExample/json/product/post");

    StringEntity input = new StringEntity("{\"qty\":100,\"name\":\"iPad 4\"}");
    input.setContentType("application/json");
    postRequest.setEntity(input);

    HttpResponse response = httpClient.execute(postRequest);

    if (response.getStatusLine().getStatusCode() != 201) {
        throw new RuntimeException("Failed : HTTP error code : "
            + response.getStatusLine().getStatusCode());
    }

    BufferedReader br = new BufferedReader(
                    new InputStreamReader((response.getEntity().getContent())));

    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
    }



  } catch (MalformedURLException e) {

    e.printStackTrace();

  } catch (IOException e) {

    e.printStackTrace();

  }

}

for each request it is taking around 6 sec and if i calculate for 10 million records it will take hours , can some one please suggest me are the any ways to improve the performance ??

thanks in advance Sunny

Use This code this will increase performance while calling REST because this uses classs of Jax api like WebResource and so on....

First, if one request takes 6 seconds, 10 million records will take 115 days. So you should reduce the response time from 6 seconds to several hundred of milliseconds first before you use some multithread tech to increase performance from cilent side.
