   Thanks @grygielski for the proposal. I definitely agree with the premise of this proposal: most users do not know/care about denormals and they just get in the way of good performance for some use cases.
   
   For ease of use, I would encourage disabling denormals by default and go for option 2 or 4 (so set FTZ and DAZ), since the users that need denormals for accuracy usually know about denormals in the first place, whereas for the general users, denormals will likely not make any difference for accuracy but will impact performance.
   
   I have no opinion on which one is the best for code simplicity/maintenance though, so I let the MXNet contributors further comment on that.
