A computer program product stored on computer storage media includes instructions for managing a workload in a computing system. The product including instructions for collecting resource and state data for a plurality of service class periods, calculating a long term execution velocity, if sufficient data exists, then determining a goal velocity using the data, otherwise, selecting a default value for the goal velocity, associating the goal velocity with the respective service class period, repeating the calculating, determining, selecting and associating for each service class period in the plurality of service class periods, and adjust the resource access to each of the service class periods according to the associated goal velocities.
