当请求被激发时,WCF请求时间会增加

我有一个服务(WCF服务托管为IIS),您可以在此处看到:

[ServiceContract]

    public interface  IInquiryService
    {

        [OperationContract]
        [WebGet(UriTemplate = "/Inquiry/{VisitDatetime}/{Plaque}", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]

        Inquiryview Inquiry(string VisitDatetime, string Plaque);
}

使用此机具:

 public class InquiryService : IInquiryService
    {
        private DataContext _ctx;
        private INajaService _najaService;
        private IUserService _userService;
        public InquiryService(DataContext ctx, INajaService najaService, IUserService userService)
        {
            _ctx = ctx;
            _najaService = najaService;
            _userService = userService;
        }

        public  Inquiryview Inquiry(string VisitDatetime, string Plaque)
        {

            !!.....service
        }
}

这是服务网络配置

因此,我使用两种方法调用此服务:

1-对于10个应用程序,每个应用程序都有一个线程(foreach()):2000个请求的所有响应时间约为200 ms。 2-对于一个具有多线程的应用程序(Parallel.ForEach):响应时间是100 ms,但当请求增加时,响应时间也会增加,我的意思是在请求的中间部分,响应时间达到5000 ms,在请求结束时,响应时间再次达到200 ms。

所以我认为在某些方面,请求、队列是创建的,但我不知道在哪里?

我的客户:

private async void btnStart_Click(object sender, RoutedEventArgs e)
        {
            btnStart.Content = "Please Wait...";
            btnStart.IsEnabled = false;

            await Task.Run(() =>
            {
                InquiryService service = new InquiryService();
                var items = Data.GetData(39000,40000).AsEnumerable();

                Parallel.ForEach(items , item =>
                {                    
                    string plaque = Plaque.GeneratePlaque(item.palll); //GeneratePlaque()//iran + "-" + ltree + lchar + ltow;
                    var result = service.Inquiry(plaque);
                    string serializedResult = new JavaScriptSerializer().Serialize(result);

                    FinalData finalData = new FinalData()
                    {
                        date = result.StartDate,
                        enddate = result.EndDate,
                        log = serializedResult,
                        plaque = plaque
                    };

                    FinalList.Add(finalData);

                    plaque = null;
                });

                //Data.InsertData(serializedResult, plaque, result);
                Data.InsertData(FinalList);

                Dispatcher.Invoke(() =>
                {
                    btnStart.Content = "Start";
                    btnStart.IsEnabled = true;
                });
            });
        }
    }

创建请求的函数:

public Result Inquiry(string Plaque)
        {
            string result_ = "";
            ServicePointManager.ServerCertificateValidationCallback += (se, cert, chain, sslerror) => { return true; };
            DateTime start;
            DateTime end;
            using (WebClient ClientRequest = new WebClient())
            {
                ClientRequest.Headers["Content-type"] = "application/json";
                ClientRequest.Encoding = System.Text.Encoding.UTF8;
                NetworkCredential credential1 = new NetworkCredential("1", "1");
                ClientRequest.Credentials = credential1;
                start = DateTime.Now;
                result_ = ClientRequest.DownloadString(ServiceHostName + "/Inquiry/2012-12-28" + "/" + Plaque);
                end = DateTime.Now;

            }
            var javascriptserializer = new JavaScriptSerializer();
            Result temp = javascriptserializer.Deserialize<Result>(result_);
            temp.StartDate = start;
            temp.EndDate = end;

            return temp;
        }

我更改了一些IIS配置,如您所见:

2000多线程请求次数:
