如何使用 JSON 加快从服务器获取数据的速度？

Question

我正在构建一个应用程序，该应用程序在 android 中使用 JSON 从服务器获取数据。有大约 3000 条记录被提取，加载似乎相当慢。获取数据的代码如下-

public static String executeHttpGet(String url) throws Exception {
        BufferedReader in = null;
        try {
            HttpClient client = getHttpClient();
            HttpGet request = new HttpGet();
            request.setURI(new URI(url));
            HttpResponse response = client.execute(request);
//          in = new BufferedReader(new InputStreamReader(response.getEntity()
//                  .getContent()));
            in = new BufferedReader(new InputStreamReader(response.getEntity()
                    .getContent(), "UTF-8"));
            StringBuffer sb = new StringBuffer("");
            String line = "";
            String NL = System.getProperty("line.separator");

            while ((line = in.readLine()) != null) {
                sb.append(line + NL);
            }

            in.close();

            String result = sb.toString();

            return result;
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    Log.e("log_tag", "Error converting result " + e.toString());
                    e.printStackTrace();
                }
            }
        }

有什么办法可以加快获取速度吗？提前致谢。
