A method for accessing a shared resource is provided. An assigned usage rate is received from a resource coordinator and a desired usage rate is determined. When it is determined that the desired usage rate is higher than the assigned usage rate, a shared resource may be accessed at an enhanced usage rate if a usage reserve has been accumulated. When a shared resource is accessed at an enhanced usage rate, the usage reserve is decremented by an amount based on a difference between the enhanced usage rate and the assigned rate. When there is no usage reserve accumulated, access to the shared resource is limited to the assigned usage rate. When the desired usage rate is not higher than the assigned usage rate, a shared resource is accessed at the desired usage rate. When the desired usage rate is less then the assigned usage rate, the usage reserve is accumulated up to a reserve maximum. The reserve maximum may be based on configuration data.
