将 Net Framework 4.7.1 升级到 Net 6 会降低 WCF 服务使用速度
Upgrade Net Framework 4.7.1 to Net 6 makes WCF service consumption slower
问：
我们正在将 .Net Framework 4.7.1 后端重写为 .Net 6，并且我们有了第一个版本。但是在本地执行性能测试时，我们观察到在相同的配置下，新后端的查询速度较慢。当使用WCF服务中的数据时，会发生这种情况：以前平均需要200毫秒，现在是650毫秒
我们在 web.config 中配置了连接的服务
<system.serviceModel>
<diagnostics performanceCounters="Off">
<messageLogging logMalformedMessages="true" logMessagesAtTransportLevel="true"/>
</diagnostics>
<bindings>
<basicHttpBinding>
<binding name="DocumentSecuredServiceBinding" bypassProxyOnLocal="false" receiveTimeout="00:10:00" sendTimeout="00:10:00" textEncoding="utf-8" messageEncoding="Mtom" maxReceivedMessageSize="209715200" maxBufferPoolSize="5242880" maxBufferSize="209715200">
<security mode="Transport">
<transport clientCredentialType="Certificate"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint name="DocumentServiceImpl" address="https://service/DocumentSecuredService" binding="basicHttpBinding" bindingConfiguration="DocumentSecuredServiceBinding" behaviorConfiguration="CredentialIdentificationBehavior" contract="DocumentService.DocumentSecuredService"/>
</client>
<behaviors>
<endpointBehaviors>
<behavior name="CredentialIdentificationBehavior">
<clientCredentials>
<clientCertificate findValue="CertName" x509FindType="FindBySubjectName" storeLocation="LocalMachine" storeName="My"/>
</clientCredentials>
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
现在，配置是从抽象工厂中的appsettings.json加载的，并实现：
public abstract class BaseSecuredServiceFactory
{
protected readonly X509Certificate2 _clientCertificate;
protected readonly Binding _binding;
protected readonly EndpointAddress _endpointAdress;
protected BaseSecuredServiceFactory(ILoggerFactory loggerFactory, EndpointOptions option)
{
_clientCertificate = LoadCertificate(option.CertificateSubjectName);
_binding = new BasicHttpBinding()
{
BypassProxyOnLocal = option.ByPassProxyOnLocal,
ReceiveTimeout = option.ReceiveTimeout,
SendTimeout = option.SendTimeout,
TextEncoding = Encoding.UTF8,
MessageEncoding = option.MessageEncoding,
MaxReceivedMessageSize = option.MaxReceivedMessageSize,
MaxBufferPoolSize = option.MaxBufferPoolSize,
MaxBufferSize = option.MaxBufferSize,
TransferMode = option.TransferMode,
Security = new BasicHttpSecurity()
{
Mode = option.SecurityMode,
Transport = new HttpTransportSecurity()
{
ClientCredentialType = HttpClientCredentialType.Certificate
}
}
};
_endpointAdress = new EndpointAddress(option.EndpointAdress);
}
protected static X509Certificate2 LoadCertificate(string subjectName)
{
// Load certificate from store My of LocalMachine
X509Store store = new(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
X509Certificate2Collection certificates = store.Certificates.Find(
X509FindType.FindBySubjectName,
subjectName,
false
);
if (certificates.Count == 0)
{
throw new InvalidOperationException(
$"The certificate with subject name '{subjectName}' could not be found."
);
}
return certificates[0];
}
}
public class DocumentSecuredServiceFactory
: BaseSecuredServiceFactory,
IDocumentSecuredServiceFactory
{
public DocumentSecuredServiceFactory(
ILoggerFactory loggerFactory,
IOptions<DocumentEndpointOptions> options
)
: base(loggerFactory, options.Value) { }
public DocumentSecuredServiceClient GetDocumentSecuredService()
{
DocumentSecuredServiceClient result = new(_binding, _endpointAdress);
result.Endpoint.EndpointBehaviors.Add(new InspectorBehavior(_loggerFactory));
result.ClientCredentials.ClientCertificate.Certificate = _clientCertificate;
return result;
}
}
appsettings.json中的配置部分

我已更新到最新版本的System.ServiceModel软件包（6.0.0）。在以前的后端，它是 4.0.0 版本。我使用了 svcUtil 版本 2.1.0
我已经比较了两个服务对象实例化，我看不出任何可以解释性能缓慢的差异
我还尝试更改一些设置并使用其他绑定（NetTcpBinding 和 WSHttpBinding）但没有成功
我们只在 WCF 服务的客户端工作
提前感谢您的帮助
编辑由于此更改，我已将新时间提高到 500 毫秒 https://github.com/dotnet/wcf/issues/5002

在WCF团队github上创建问题后，提出了两种解决方案：
- 使用 HttpClientFactory，但它需要对我们的代码进行大量修改
- 在第一个客户端实例之前添加。我们这样做了，性能比我们当前的 API 更快
