I've just started using intel VTune Amplifier XE and looks like by default only cpu-time measures. Is it possible to setup VTune to get results based on wall clock time (real time)? Actually my goal is to get hotspots from disk I/O operations.

    Maybe you've seen [*this*](http://stackoverflow.com/a/378024/23771). It finds speedup opportunities, whether I/O or not. – Mike Dunlavey Jul 21 '16 at 12:59

To measure I/O of the app in VTune you can use two features. Locks and Waits Analysis to trace APIs which are blocking you app execution (including I/O API) or dedicated Disk Input and Output Analysis to see if you are blocked on the disk and what APIs in the app are causing that.
