  The paper is based on Noar's model of charged queues. We extend this model
into multi-server systems with information about length and service rate
disclosed for all the customers, and the customers can choose the optimal
options. We discuss whether the splitting strategy of the server resource could
bring more revenue for the service provider. We prove that any G/D/1 server
supplier cannot earn more revenue by splitting his resource under the
equal-toll limitations.
