Java Httpurlconnection

[Somshekar C Kadam]

Hi All,
Even if I try this simple httpsurlconnection java program to print content
it takes more than 10 seconds on ARM not in intel. Not sure why please help

HttpsClient.java
========================
import java.net.MalformedURLException;
import java.net.URL;
import java.security.cert.Certificate;
import java.io.*;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLPeerUnverifiedException;

public class HttpsClient {

   public static void main(String[] args)
   {
        new HttpsClient().testIt();
   }

   private void testIt(){

      //String https_url = "https://www.google.com/";
      String https_url = "
https://transparencyreport.google.com/https/overview?hl=en";
      URL url;
      try {

    url = new URL(https_url);
    HttpsURLConnection con = (HttpsURLConnection)url.openConnection();

    //dumpl all cert info
    print_https_cert(con);

    //dump all the content
    print_content(con);

      } catch (MalformedURLException e) {
    e.printStackTrace();
      } catch (IOException e) {
    e.printStackTrace();
      }

   }

   private void print_https_cert(HttpsURLConnection con){

    if(con!=null){

      try {

System.out.println("Response Code : " + con.getResponseCode());
System.out.println("Cipher Suite : " + con.getCipherSuite());
System.out.println("\n");

Certificate[] certs = con.getServerCertificates();
for(Certificate cert : certs){
  System.out.println("Cert Type : " + cert.getType());
  System.out.println("Cert Hash Code : " + cert.hashCode());
  System.out.println("Cert Public Key Algorithm : "
                                    + cert.getPublicKey().getAlgorithm());
  System.out.println("Cert Public Key Format : "
                                    + cert.getPublicKey().getFormat());
  System.out.println("\n");
}

} catch (SSLPeerUnverifiedException e) {
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}

     }

   }

   private void print_content(HttpsURLConnection con){
if(con!=null){

try {

  System.out.println("****** Content of the URL ********");
  BufferedReader br =
new BufferedReader(
new InputStreamReader(con.getInputStream()));

  String input;

  while ((input = br.readLine()) != null){
     System.out.println(input);
  }
  br.close();

} catch (IOException e) {
  e.printStackTrace();
}

       }

   }

}
