Yes, creating ConfigurationContext is very expensive since it involve reading various files. So as Thilina mentioned create a ConfigurationContext and use the created ConfigurationContext for subsequent call. Simply when you create the stub pass the same configuration context.
However when you use this approach, do not forget to cleanup the transport. You can do that by getting the service client from the stub, and calling its cleanup transport method.
