YMMV. For testing purposes it would be nice to have a one-line summary for each device containing a thread ID, start timestamp, end timestamp, and elapsed time. With that information you could evaluate the amount of parallelism and determine where the bottlenecks are. It would give a much more detailed picture of the entire process than the total time of your recent patch 9.
