A computing system and a method for self-tuning a computing system. The method includes executing a current workload of the computing system until completion of the current workload; measuring a current operation metric representing a current operation performance of the computing system; tuning each of the plurality of system knobs to a static value selected from a group of static values; and iteratively executing the current workload of the computing system until an exit condition is met, wherein the exit condition is met when operation of the computing system having the system knobs tuned to one of the selected static values is an optimal static value satisfying at least one predefined target metric.
