Matrix Multiply slower on RT than PC?


Recommended Posts

I was playing with large matrices and was testing execution speed on my laptop (the code is destined to run on RT). 


The code below tests using the Matrix Multiply function vs just straight array math.  Unsurprisingly the Matrix Multiply function executed faster.  Then when I ran it on RT both methods took the same amount of time? And Matrix Multiply (A x B.vi) takes LONGER on RT than PC?  Is there some windows-optimized code under the hood that is not available on RT?


I was hoping it would be faster since my laptop is several years old and this is NI's super duper 8135 PXI controller. I did deploy this as a startup app to ensure running from the IDE did not affect timing when running on the RT.
