OS Optimization Reducing Boot Time through the RegistryĬlean the Registry Registry = Database Useless data clogs the registry Requires more memory to load Increases boot time Slower application loads Tool: Registry Scrubber - RegScrubXP.exe Remove left over, unreferenced values/keys Ĭompress the Registry Expanded registry Requires more time to reference More space on disk More time at boot time Tool: Registry Optimizer - NTRegOpt.exe Compresses the registry file – eliminates file space gaps ![]() Press 'ok.' Tool: Prefetch Cleaner Disable Prefetch Prefetch System only Prefetch Apps only Right click the shortcut and hit 'properties.‘ In the 'target' box, put '/prefetch:1' at the end of the line. Tune the XP Prefetcher Prefetcher can help or hurt performance Proactively loads apps during boot to improve load performance Load apps at boot time Some apps have a '/prefetch:1' switch. Parallelize boot sequence TOOL: Bootvis.exe Logs every driver/service loaded at boot Times each load Analyzes software loaded in log Provides “boot intelligence” Enables viewing of software loaded Graphs time-to-load for each driver Auto-optimizes boot sequence for fastest performance (Some drivers load in parallel) Optimize boot sequence TOOL: Bootvis.exe Logs every driver/service loaded at boot Clocks each for load time Provides “boot information intelligence” Enables analysis of software loaded Graphs time-to-load for each driver Auto-optimizes boot sequence for fastest performance enables drivers to load in parallel (Note: Windows XP does this optimization operation 24 hours after installation automatically) Uninstall unneeded fonts Fonts increase boot time Loaded at boot Most people don’t know which fonts are useful Tool: FontXplorer Visually displays fonts Determine which to keep or dump Removing apps/resources Apps may load boot time stubs Quicktime Real Acrobat Every hardware resource needs a driver & load time Serial or Parallel port? Onboard video? Onboard IDE/SCSI? USB? Firewire?
