使用Httpclient访问url，如何提高服务器响应速度？

Question

 HttpGet httpGet = new HttpGet(spliceurl);

 CloseableHttpClient httpClient = HttpClients.createDefault();

 RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout((int) (80000)).setConnectTimeout((int) (20000)).build();

 httpGet.setConfig(requestConfig);

 response = httpClient.execute(httpGet);


 content=EntityUtils.toString(response.getEntity(), "utf-8");

它总是告诉我：java.net.SocketTimeoutException：读取超时。 但是当我测试单个网址时，它的响应是及时的。那么，谁能说出问题是什么？
