"Concerning GZIP encoding, each JAX-RS provider has different approaches"
Jersey provides a filter to accomplish the encoding transparently:
http://jersey.java.net/nonav/apidocs/latest/jersey/index.html

RESTEasy provides an annotation for that:
http://docs.jboss.org/resteasy/2.0.0.GA/userguide/html/gzip.html

I don't have my own code. I've never done this. found this on i-net :

// The response is gzip encoded, so decompress the response.
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        response.writeTo(out);
        byte[] barr = out.toByteArray();
        InputStream gzipStream = new GZIPInputStream(new ByteArrayInputStream(barr));
        Reader decoder = new InputStreamReader(gzipStream, "UTF-8");
        BufferedReader buffered = new BufferedReader(decoder);
        int n = 0;
        char[] cbuf = new char[1024];
        Writer w = new StringWriter();
        while ((n = buffered.read(cbuf)) != -1) {
            w.write(cbuf,0,n);
        }
        // the writer now contains unzipped message.
        System.out.println(w.toString());

Yor code should like this :

      conn.setRequestMethod("GET");
                conn.setReadTimeout(600 * 1000);
      conn.connect();
      long end2 = System.currentTimeMillis();
      System.out.println("time taken connection : " + (end2 - end1) + " ms");
      if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "+ conn.getResponseCode());
      }
      is = conn.getInputStream();
      InputStream gzipStream = new GZIPInputStream(in);
      Reader decoder = new InputStreamReader(gzipStream, "UTF-8");
      br = new BufferedReader(decoder);
      stringBuilder = new StringBuilder();

                  String line = null;
                  long startRead = System.currentTimeMillis();
                  System.out.println("time taken  ========: " + (startRead-end2) + " ms");
                  while ((line = br.readLine()) != null) {
                        stringBuilder.append(line + "\n");
                  }
