The virtual waiting time technique is introduced as a solution to the problem of a controller distributing work to servers of different speeds. The servers are considered to be part of a distributed system without feedback. The virtual waiting time technique is shown to minimize the average completion time for a job distributed by the controller. The virtual waiting time technique does not depend on any arrival distribution and is applicable to any service time distribution. The performance of the technique is examined for different arrival and service time distributions.
