This is a nice video that discusses the basics of performance monitoring in windows. This is actually a live class that I taught to a group of developer/admins and just decided to record it. We got cut off there at the end for time, but the next version is coming soon. There’s a lot of stuff on perfmon counters, Task Manager, command line tools for monitoring and killing tasks, loading and unloading perfmon counters, etc. There’s lots of good stuff in here.
