I am trying to optimize a driver for performance. What are the standard way= s to profile a driver? My problem at the moment is that when I run a test and max out the CPU, then the system % is 60 and user % is 30. I wanted to find out how much tim= e is being spent in the driver(and within it, if possible in what components)= . Can this be determined and if so, how to figure this out.
