CUDA streams taking longer time

Is is possible that streams take longer time than normal CUDA programs?It is guaranteed that chunk of data on which streams are operate are independent and overlapping between kernel execution and data transfer is allowed from device side.

To observe superpositions between streams, you should use the command line profiler with the conckerneltrace option. You could also save the profiling output as a .csv file and import it within the Visual Profiler. See the NVIDIA Forum post
