We consider the problem of disk scheduling to enhance disk performance. We introduce a new algorithm (SLOOK) for offline optimal performance, in terms of total seek time, and test it in online situations using a preemptive approach. In addition, we build a simulator for disk requests generation
(DiskSims) to experimentally test our proposed algorithm and provide a comprehensive comparison with popular disk scheduling algorithms. Experimental results demonstrate that our algorithms achieve promising behavior.
