Benchmark LabVIEW MathScript against LabVIEW Low Level VI's


This example demonstrates how to benchmark the FFT execution time between native LabVIEW FFT VI and LabVIEW MathScript Node.



This VI runs a side by side comparison of the time taken to perform an FFT in both MathScript and using low level LabVIEW VI's.

It contains an image of the results from a Quad Core machine and allows a configurable test to be run.



  • LabVIEW Full Development System 2012 (or compatible)
  • LabVIEW MathScript RT Module 2012 (or compatible)


  • No hardware is necessary to use this example VI


Steps to Implement or Execute Code

  1. Download and open the attached file
  2. Run the program
