需要在两个 .NET 进程之间快速且频繁地进行通信

所以我有以下设置：

一方面使用 .NET dll 的 VB6 应用程序，另一方面
使用 .NET 服务

VB6 应用程序使用一个小的接口 dll 与我们的新基础设施（服务等）进行通信，并且几乎无法更改在功能上。我们选择使用带有这样的绑定的 WCF

<system.serviceModel>
    <client>
      <endpoint address="net.tcp://localhost:8001/HostCommunicator" binding="netTcpBinding" bindingConfiguration="NETTcpBinding" contract="IHostCommunicationContract"/>
    </client>

    <bindings>
      <netTcpBinding>
        <binding name="NETTcpBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false"/>
          <security mode="Transport">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </netTcpBinding>
    </bindings>
</system.serviceModel>
  <startup>

来进行通信。

对于单个请求来说，这工作得很好而且很快，但 VB6 应用程序的一种模式是一种批处理模式，它为它处理的每个文件发送一个单独的请求。每秒大约会有 1-4 个请求。

在完成许多请求之前，这种方法可以正常工作。在我当前的机器和软件版本上，这是 50 个请求。如果我启动 VB6 应用程序，它会再次执行 50 个请求。超过限制后，应用程序会在 CPU 使用率达到 99% 时挂起。

我们正在使用双工通道合约。

原文

So I have the following setup:

a VB6 Application using a .NET dll on the one hand
a .NET Service on the other end

The VB6 application uses a small interface dll to communicate to our new infrastructure (servies etc) and can hardly be changed in functionality. We choose to use WCF with a binding like this

<system.serviceModel>
    <client>
      <endpoint address="net.tcp://localhost:8001/HostCommunicator" binding="netTcpBinding" bindingConfiguration="NETTcpBinding" contract="IHostCommunicationContract"/>
    </client>

    <bindings>
      <netTcpBinding>
        <binding name="NETTcpBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false"/>
          <security mode="Transport">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </netTcpBinding>
    </bindings>
</system.serviceModel>
  <startup>

to communicate.

This works fine and fast for single requests but one mode of the VB6 Application is a kind of batch mode where it sends an individual request for each file it processes. There will be about 1-4 requests per second.

This works fine until a number of requests is done. On my current machine and software version this are 50 requests. If I start the VB6 application over it does 50 requests again. After the limit the application hangs at 99% CPU usage.

We are using a duplex channel contract.
