许多请求的httpclient超时

为了模拟一个包含许多用户的web应用程序，我使用了for循环，我知道它仍然非常不同，因为这将是单线程和所有这些。我的代码在下面

To simulate a webapplication with many users, I have used a for loop, I know still its very different as this will be single thread and all that. My code is below

public CloseableHttpClient getHttpClient() {
        try{
            SSLContext context = null;
            TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return null;
                }

                public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
                }

                public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
                }
            } };

            try {
                context = SSLContext.getInstance("SSL");
            } catch (NoSuchAlgorithmException e1) {
                e1.printStackTrace();
            }
            try {
                context.init(null, trustAllCerts, new java.security.SecureRandom());
            } catch (KeyManagementException e1) {
                e1.printStackTrace();
            }

            SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory> create()
                      .register("https", sslConnectionFactory)
                      .register("http", new PlainConnectionSocketFactory()).build();

            PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(socketFactoryRegistry);
             // Increase max total connection to 200
             cm.setMaxTotal(20);
             // Increase default max connection per route to 20
             cm.setDefaultMaxPerRoute(10);
             RequestConfig defaultRequestConfig = RequestConfig.custom()
                        .setSocketTimeout(5000)
                        .setConnectTimeout(5000)
                        .setConnectionRequestTimeout(5000)
                        .build();
             CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(cm).setConnectionManagerShared(true)
                     .setDefaultRequestConfig(defaultRequestConfig).build();
            return httpClient;
        }catch(Exception ce){

        }
        return null;
    }

然后在循环中我使用它如下

Then in loop I am using it like below

try{
for(int i=0;i<500;i++){
                client = getHttpClient();
request = new HttpPost("Some https URL");
              HttpResponse response = client.execute(request);
              int statusCode = response.getStatusLine().getStatusCode();
 if (statusCode == 200 ){
                    entity = response.getEntity();
                    String content = EntityUtils.toString(entity);
}
                else{
                    entity = response.getEntity();
                    String content = EntityUtils.toString(entity);
}}
catch(Exception ce){}
finally{
                  try {
                        EntityUtils.consume(entity);
                        request.releaseConnection();
                        client.close();
                        } catch (IOException e) {
                    }
              }

我得到几个请求的响应，而少数读取超时失败，如果我增加最大连接我得到几个失败如果我在连接管理器中保持max conn为200仍然我得到的失败但没有这个配置那么多，什么是我失踪了。以下例外

I get response for few request whereas fail for few with read timeout, if I increase the max connection I get few failures If I keep max conn as 200 in connection manager still I get few failure but not as many as with this config, WHAT is that I am missing. Exception below
