We investigate the ability of these scheduling policies to increase BG/L utilization and decrease job waiting time . We perform some of experiments to measure performance criteria LJF achieves better utilization than SJF in simulation experiment but in real experiments it accomplishes the best utilization and average waiting time ER -
