Usually if you ran application shortly, there is no result to how. Please add more workloads in your program.

Maybe your application run so fast(short period of time) and was below the measurement threshold.I experienced such a behaviour.

Default interval time is 10ms. You might copy from Hotspots analysis to create a new custom analysis - change interval value to 2ms if you like.

Thanks Peter.

Can I change time measurement interval to even lower value for example in range 0.1-0.2 msec , because I'm testing a FFT alghorithm which finishes execution of its code very quickly ~125000 nanosec?In order to perform precise timing I needed to increase data set size to more than 4096 points.

No. 2ms is minimal value for interval, I recommend.

Thank you Peter.
