ABSTRACT:
Launch time for a computer program is reduced by logging hard disk accesses during an initial launch, then processing the log file to accelerate subsequent launches. The log file is processed by identifying all the file portions accessed during the launch, eliminating any duplicate cluster accesses, then sorting the remaining accesses. The disk access log entries are sorted by physical address or are grouped by file, then organized by logical address within each group. The processed log file is stored with the application program. When the application program is launched thereafter, the processed log file is accessed first. All the disk accesses in the log file are performed moving all the data into RAM cache. When the program launch resumes, the launch occurs faster because all the data is already in cache.
