我对 WCF 有点陌生，获取记录的调用需要将近 20 秒，即使在调试期间进行本地调用也需要花费时间。它正确完成，但速度很慢。

客户来电：

var docImgSvc = new DocImagingService.DocImagingStatusServiceClient("WSHttpBinding_IDocImagingStatusService");
CurrentManifest = docImgSvc.GetManifest(manifestLookup);  //<<---This takes 20 secs
if (CurrentManifest == null || CurrentManifest.ManifestId == 0)

服务器例程：

public Manifest GetManifest(int manifestNumber)
{
    var de = new DocumentImagingEntities(); //<<---Takes 20 secs before it gets here.
    var manifest = de.Manifests.FirstOrDefault(m => m.ManifestId == manifestNumber);
    return manifest;
}

服务器配置：

  <system.serviceModel>
<services>
  <service name="DocImagingServices.DocImagingStatusService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/Design_Time_Addresses/DocImagingServices/DocImagingStatusService/"/>
      </baseAddresses>
    </host>
    <endpoint address="" binding="wsHttpBinding" contract="DocImagingServices.IDocImagingStatusService">
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

    <behavior>
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

客户端配置：

  <system.serviceModel>
<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IDocImagingStatusService" closeTimeout="00:01:00"

以前，当我看到这种类型的响应时间时，它是由于应用程序池设置造成的。

有一个设置允许您在运行应用程序池时加载用户配置文件，这个加载时间可以匹配您的 20 秒。

请参阅http://blogs.msdn.com/b/vijaysk/archive/2009/03/08/iis-7-tip-3-you-can-now-load-the-user-profile-of-the-application -pool-identity.aspx有关如何设置此值的屏幕转储。
