PerfTrack is the feedback and monitoring system inside of Windows 7 that performs measurements on, well, all things related to the overall performance of the OS, especially as it relates to system responsiveness to user actions. So, when you click on something (an icon, a folder name, etc...), how long does it take for the user to receive an expected reaction from the system? What are the bottlenecks that lead to a poor experience (user-observable latency) when using some feature in Windows? Is the root problem in the design of the feature itself or with the underlying OS? Enter PerfTrack.

Here, Development Manager David Fields and Group Program Manager Bill Karagounis share their wisdom and experience in the world of OS performance analysis. David and Bill explain how PerfTrack works and we digress into an interesting conversation about power management.

PerfTrack is an example of a technology that provides incredibly important real-world information to Windows engineers that can be used to solve performance problems in Windows.

Enjoy!

Perftrack mentioned here just used internally at Microsoft ? Are they any similar benchmark programs ? is this part of the undocumented APIs?
