While not appropriate for most users, the tools are quite useful to developers, geeks and performance enthusiasts. The Windows Performance Toolkit can be used to analyze performance during startup, boot up, deferred procedure calls and interrupt activity (DPCs and ISRs), system response, resource usage, and interrupt storms. This feature requires 23.8 MB of hard disk space. The WPT is available for download here:
