VSTS Dual Server Performance problem

We have 2 environments of VSTS – one single server and the second dual server.

We are encountering performance problem (During checkout, check-in operation) in the dual server configuration (the operation are performed from a client that is installed on the server (it eliminates a network problem) only.

Is there is any additional server configurations that we should consider (and that is not mentioned in the installation guide).
