Start Async Call behavior in a timed loop?

[ConnerP]

So I have some questions about Start Async Calls in timed loops. First and foremost, do they inherit the priority of the loop? Secondly, do Start Async Calls fire off immediately as if a subvi were there on the block diagram, or is there significant overhead there?

It should be simple enough to write a little VI to test this -- if you did this, you could reply to your Post and "Mark it as a Solution".  I would be surprised if the Priority was inherited, and if the overhead in starting the Call was non-trivial (my definition: > 10 microseconds).  To mis-quote Ronald Reagan:  "Test, and Verify."
