Hello all
I want to shift my processing algorithms from VSC++ to Labwindow/CVI however, one strange problem i am facing is the significant execution speed difference b/w VS and CVI. One such example is of FFT. In Microsoft Visual Studio 2010 VC++, i am using FFTW libraries for FFT execution of say 65536 points array in a loop of 100 iterations. It takes roughly 30-47ms for execution for this process on core i5 processor. Now for NI LabWindows CVI 2012 on same processor, i have used FFTEx (with reusable FFT table calculated using 'CreateFFTTable' one time before loop iterations) for same no of points and iterations and it takes roughly 210-217ms for execution for this process.
Is this normal or i am missing something?
Thanks
