WCF listenBacklog and maxConnections can't be set higher than 10. Why not?
- by NeedWCFPro
My service works great under low load. But under high load I start to get connection errors.
I know about other settings but I am trying to change the listenBacklog parameter in particular for my TCP Buffered binding.
If I set listenBacklog="10" I am able to telnet into the port where my WCF service is running.
If I change listenBacklog to anything higher than 10 it will not let me telnet into my service when it is running.
No errors seem to be thrown.
What can I do?
I get the same problem when I change my maxConnections away from 10. All other properties of the binding I can set higher without a problem.
Here is what my binding looks like:
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_IMyService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288"
maxBufferSize="1048576" maxConnections="10" maxReceivedMessageSize="1048576">
<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" protectionLevel="EncryptAndSign">
</transport>
<message clientCredentialType="Windows" />
</security>
</binding>
...
I really need to increase the values of maxConnections and listenBacklog
