My project has a netTCP WCF service.
This is the app.config for it:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_IIndexer" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"

                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <reliableSession ordered="true" inactivityTimeout="00:10:00"
                        enabled="false" />
                    <security mode="None">
                        <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
                        <message clientCredentialType="Windows" />
                    </security>
                </binding>
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://mach1:9000/Indexer" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IIndexer" contract="in.IIndexer"
                name="NetTcpBinding_IIndexer" />
        </client>
    </system.serviceModel>
</configuration>

Is there any thing that can be done to maximize the compression of the data being sent over the wire? My project is internal so speed and processing power are essentially of no issue.

What are some good tips and tricks to compress the data sent from the client to the WCF service?

    The message encoding specified by the binding will determine how your data gets turned into bytes on the wire. For the NetTcpBinding, it will automatically use binary encoding which gives you the most compact representation of your message out of all the built-in WCF encoders.

    For more information, I would recommend these resources:
