BOOTING OPERATING SYSTEM OF SYSTEM BY USING READ AHEAD TECHNIQUE, PREFETCH CONTROLLER, STORAGE DEVICE, METHOD, PROGRAM AND COMPUTER READABLE STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To reduce time required for booting a system.;SOLUTION: A method comprises generating a list of files accessed during an operating system boot process (OS boot process) to profile the OS boot process, and optimizing the list of files to generate an optimized file list for use in future OS boot processes, where the optimization is performed according to a first optimization technique if the files were accessed from a solid state medium and according to a second optimization technique, such as a rotational delay minimization and a read ahead technique if the files were accessed from a rotating medium.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
