Need to communicate quickly and often between two .NET processes

Question

So, I have the following setting:

• VB6 application using .NET dll, on the one hand
• .NET service on the other end

The VB6 application uses a small DLL interface to communicate with our new infrastructure (services, etc.) and is unlikely to 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>

for communication.

This works fine and fast for single requests, but one VB6 application mode is a kind of batch mode when it sends an individual request for each file being processed. There will be about 1-4 queries per second.
