OK, so it tells you how a very poorly written application - one which probably shouldn't be running on such a system in the first place - will perform. And it's useless for everyone else. Here, have an internet point.
Thanks for whatever it is that you gave me. I don't keep up with nomenclature these days.
Using dd in this role and then complaining about the result before running any other kind of test is a waste of everyone's time. No filesystem, even local, is optimized for that kind of performance. You do know the difference between performance and scalability, don't you? People who evaluate server-oriented systems in 2017 based on a methodology more appropriate for a 1997 desktop are doomed to fail. In everything.
